X4 if it happens will almost certainly be adaptian of days of Future Past.
The question remains will The Last Stand be In contunity or not.X4 or
X

ays of future past will come no earlier than 2014.Bryan Singer will be
working on Jack The Giant Killer till December 2012.And even If they keep
The Last Stand In Conituity they will not want to make references to stuff
In The Last Stand.There will be no references to the Cure.And Xavier would
likely be back with no mention of this being new body.
There will certainly not be all the cast back as they were able to do for the Most part for The Last Stand.Remember they had to renegorate deals for most of the cast after X2.
X-men-I see this as most likely Lineup
Xavier
Wolverine(If Hugh jackman plays Wolverine again after The Wolverine It will
be for X-Men sequel)
Rogue
Iceman
Colossus(Recast)
The Angel
Gambit will likely be reintroduced Ignoring Wolverine.If The last Stand Is
Ignored I can see Cyclops as part of Lineup.
Rogue will likely take the role Kitty Pryde took In original story.
Even If Last Stand Is still In Canon they can say the trask In Last Stand was
not Boliver trask.
I could see Older Emma Frost(similar to Singer's Idea for X3) or Sinster
having group to kill human leader.
I think you guys are all exercising in wishful thinking.
They are not going to expunge
X3: The Last Stand from the film continuity....definitely not.
This is a flick that made the studio $450 million world wide....it wasn't a flop...in fact, it was the fourth biggest film of the year it came out and the TOP earner of the X-men Film Series.
Still, they can work out the issues from the third film if they want to.
Trask WAS Bolivar Trask...plain and simple. Yeah, there are
two men with the last name Trask working for the government? Please. They can just have the cure showdown be an "aha moment" for him. Jean caused a
lot of destruction and killed a
lot of people. He'll see that someone needs to protect the humans in this conflict. He begins work on "Project Wide Awake" and creates the Master Mold.
Xavier can be in Scotland with Moira, not fully knowing who he is
or have him taken captive (in his weaken state) by one of the films villains (Mr. Sinister, perhaps).
Scott can also be enslaved by Sinister...this would remain true to the character's history. That,
or have Jean moved him somewhere desolate and he finds his way back to the team by the mid point of
X-Men 4.
Colossus doesn't need to be recast...Cudmore is a serviceable actor for the part. If they want the accent (which if Singer directs, I don't think he will. After all, Cudmore
wanted to use the Russian accent in
X2: X-men United but Singer vetoed it).
Magneto, we saw, is regaining his powers....but this will be slow. I think the story options of a de-powered, vulnerable Magneto are cool. They can either give the aging McKellen a break, and not ask him back for the fourth installment, or they can have him come to the X-men for help, now that he is weak....and they are aligned against a common foe. And ultimately have him come back fully powered in the final film of the series.
There are so many villains that we can still see:
- The Morlocks
- Shadow King
- Omega Red
- Mr. Sinister
- A "new Brotherhood": Avalanche, Scarlet Witch, Quicksilver
- The Sentinels
- Graydon Creed (And the Friends of Humanity, maybe have Stryker be their inspiration...)
- Bolivar Trask
- Bastion
- Nimrod
And more.
There are some corners that they have been written into, but no more so than they are by the choices of mutants in
X-men Origins: Wolverine, or
X-Men: First Class.
They don't need to recon....they just need to get creative.
