Canemacar, eh? I hope he hasn't spoken ill of me there.

I know that ProfeZZor X mentions me from time to there too...
As for information on X-Men's cancellation, I was told by Mike Carey himself, both in person (I've got a photo of me meeting Mike) and via email, but there's no way to prove that for sure unless I forward my email conversation, and I'm pretty sure he wouldn't appreciate that.

So you'll just have to take my word for it. However, I have posted bits and pieces of my email conversations online, both on this board and Comixfan (I go by UniAniGi there).
Or maybe you don't have to have my word to go on alone. There's an ample amount of interviews hinting at X-Men's impending cancellation, starting with
X-Position #11 on this site. Specifically, question #5.

5) Mike, I believe you said on a previous edition of X-POSITION, “Humberto and Chris are going to alternate on X-Men for the whole of my run.” Have plans changed now that Ramos will be on “Runaways” and Bachalo will be on “Amazing Spider-Man” for an arc? If so, who will the new artists be and what does that statement mean for your future on the “X-Men”?
Mike Carey said:
Hmm. Good question, which is hard to answer right now. Plans have changed, because the shape of the X-verse after “Messiah CompleX” has now been planned out in more detail and we know where all the pieces are going to fall. I'm still going to be writing an X-book, but I can't be specific right now about exactly how that's going to work. There will be an announcement soon.
Instead of saying, "I'm still going to be writing X-Men", he said, "I'm still going to be writing an X-Book."
So, although he didn't flat-out say it, he did imply it.
We've found out what that X-Book would be earlier this month, from the article titled "Messiah Coming"; it's a maxi series solo/loose team up of sorts featuring a character who's been around practically since the beginning, and has never had his/her own solo before. The cast so far has been unrevealed, but most clues seem to be pointing at Xavier, and Rogue's been implicated to end up in this series as well (and maybe Gambit). Magneto's also another character that could show up, since if Xavier does indeed find him in this current arc of Uncanny or during Messiah Complex, he'd probably stay in his company by crossover's end, most likely with the Acolytes in tow. It's also been said that this title might have the chance to achieve ongoing status. Most likely, the criteria is how well this book sells. Personally, I hope it sells well to insure that Mike will continue writing an X-book.
I know it doesn't make sense to be cancelling the title and coming out with a bunch of new books in its place (X-Force and whatever Mike's new series is going to be called), but that's where all the arrows seem to be pointing, Nick Lowe's, "who said there's even going to be an X-Men after this (Messiah Complex)" is also extremely suspect.
What they seem to be doing is streamlining the main X-titles, keeping Astonishing for Ellis, and making Uncanny the official flagship title. Rumor has it that it'll ship two times a month. There's no real proof for this though, it's mainly common fan speculation.
As for X-Factor and New, while they do sell far less than X-Men, they are both very unique from the "main" X-Titles in terms of structure, purpose and mission. It's been confirmed that X-Factor will indeed be around post-crossover, since PAD said that his cast will be losing one character and gaining another ( I don't remember where he said this though), and from a few of the latest interviews, we know that the character he's losing is Rahne, to X-Force.
New X-Men's future is also uncertain, since Craig Kyle and Chris Yost haven't said anything yet about this title's future, but it's rumored that they're going to write X-Force since they're taking their creation there (X-23). But rather than being cancelled, it's more likely to be revamped with a new creative team, and renamed yet again to New Mutants.
I'm sorry I couldn't show you anything concrete, my hands are sorta tied in that regard. I know all I've given are a bunch of rumors from other fans, but they do add up.
Hope this clears things up.
