One of the newspapers claimed that the X-Mansion existed, and thus the X-Men (although they were still a sort of "urban legend" to the mainstream media - "school of mutants?" or words to that effect was a headline). So in the world of A:EMH, the X-Men do exist (as well as the Fantastic Four). Logan, as James Howlett, was one of Jack Fury's Howling Commandoes back in WWII and fought in the same battle as Cap & Bucky. But we don't know for sure if W&TXM shares the same continuity as A:EMH. Just because the X-Men exist in the same world as A:EMH isn't enough. I mean, according to those newspapers, Man-Thing, Punisher, and Ghost Rider (I believe) also exist on this world. The MRD, or "MARTIES", also exist (they were mentioned once or twice), but again, until there is harder evidence, I wouldn't be expected Cyclops to show up with his gray trench-coat quite yet.
(In W&TXM, only the Hulk appeared, and he battled Wolverine. Nick Fury also existed but he looked quite a bit different in terms of character design. Bobby Drake played an IRON MAN video game on a TV once. In fact the only definite link is during the "BREAKOUT", the Wendigo looked exactly like it did in the Hulk episode of W&TXM, and in that episode, Nick Fury and SHIELD had been experimenting to create their own metahumans and basically created more Wendigo.)
And no, Colossus did not appear in the show much. He was in the pilot episode for a few minutes, and Mystique took his form in episode 8, but aside for that, nada. He was the sole member of the core team introduced in the pilot who did not return in Season One. No one seemed to miss him, but then again, the X-Men seemed to get over missing members real quick in that show. Once Warren became Archangel, it only took half an episode for the rest of the X-Men to abandon trying to "free" him and just treat him like any other adversary. When Cyclops refused to believe that Jean was dead and could have been alive somewhere (as Xavier turned out to be), he was mostly treated like a whiner and a psychopath. When Cyclops was later the only X-Man who balked at the idea of destroying Phoenix, Xavier literally dismissed him in a psychic conference call. Not even Wolverine seemed to miss Jean much, which to me seemed a bit out of character.
I wouldn't call W&TXM "Chris Yost's baby". He wrote for the series but he was not the story editor for that show. Craig Kyle and Josh Fine had more to do with the show overall than Yost did, at least in the debut season. Kyle is now writing for film and that leaves Fine here. Yost probably had more control over "FANTASTIC FOUR: WGH" where he seemed to share duties with Kyle than on W&TXM.
If W&TXM does share the exact continuity as A:EMH, than it would at least make it easier to insert Scarlet Witch at some point. Quicksilver was still very much a villain by the end of the series. But for all we know, the X-Men who exist in A:EMH's world are an earlier roster, or all this may take place before the team disassembled for a year.
It's a few pages ago, but I may as well comment on it now. I greatly enjoyed "X-MEN EVOLUTION". It helped that it came one as I was just entering college and just getting into comics again as a weekly habit. Sure, there are a lot of funky things wrong with that world if you're a stickler for making cartoons strict adaptations of the comics. I accepted the differences because it was coming out at the same time as ULTIMATE was still new, and the 90's X-MEN series was already based heavily on the then-current comics. I didn't mind the idea that Ororo and Logan were instructors with Xavier while virtually everyone else was a teenager (aside for Hank McCoy, who rejected X-Men stuff until he couldn't hide his mutation anymore). I thought the show was very well written, especially in terms of the characters. Some of the plots of the week or the threats they faced were sometimes mundane, but I thought the characterization was strong. However, when things did get intense, it was a show to behold. I liked the designs for the most part and I also liked how Wolverine still was the adult who got the most focus (he got at least 1-2 episodes every season, something neither Xavier or Storm got), he didn't completely hog the show. If anything, the amount of times he got stuffed in a fight was borderline annoying, that's how little he hogged. He lost virtually every fight he was in, just because he could heal, he was the one who could survive massive damage. The show had the best versions of Cyclops and Rogue, at least in my opinion.
Cyclops was pretty much what you'd expect of him, only without being a dip****. He was more comfortable in the Danger Room or in an X-Men mission than in a social life, but he wasn't perfect and still made mistakes (and admitted he did so at times). He was usually Xavier's "teachers pet", but he wasn't so rigid that he never told a joke, never cranked the radio too loud or never got lazy. Even Jean wasn't so bad in Evolution; still a "good girl" as one would expect, but with a little more assertiveness, more of a big woman on campus. EVOLUTION was actually the show that got me to like Cyclops as a character.
As for Rogue, while I liked the version from the 90's, I never quite understood why she was such a flirt while in the end she could never touch anyone. It made her come off as a tease. Plus, her "actual" mutant powers usually were second fiddle to her absorbed Ms. Marvel powers. In the 90's show they went with that origin, but it was awkward. Ms. Marvel shows up for that episode flashback and for that plot, and never again. It's two seasons in before you even learn those weren't Rogue's natural powers, if you were unaware. Aside for Captain America, no other superheroes showed up beyond a blink and miss cameo in the 90's series (Spider-Man and Black Panther had those). It made sense to me that the Rogue in Evolution was more introverted. It would have been too awkward to do the Ms. Marvel origin and to be honest, Rogue was THE most powerful character in EVOLUTION anyway. No one could resist her touch, not even Magneto. She could gain multiple abilities at once and even was the lone figure responsible for saving the day in the series finale. They did homage the 90's era Rogue, as there were times she gained the ability to fly, or have super-strength, depending on who she touched.
In X-MEN EVOLUTION, the X-Men rarely were attacked with "power dampening technology". In fact off the top of my head I can't think of any one time their powers were shut off with a gizmo. The only time that came close to happening was when Leech was introduced, and he could shut off all power within a radius, including mutant powers. Beast wasn't about to experiment on a kid (who in Evolution actually did have a caring mother) to benefit Rogue, and Rogue couldn't exactly ask a ten year old kid to always be about nine feet from her so she could mack on people.
X-MEN EVOLUTION remains the longest lasting X-Men cartoon of the 21st century (and at 52 episodes, is one of Marvel's longest lasting shows period) and still remains popular online. I certainly enjoyed the hell out of it.
As for A:EMH, I am sure we will get Vision soon, but we need to get Ultron first, and they're building him up. Have patience. The last Avengers cartoon started out with Vision in episode 1 and it didn't do any favors.
