Given all the speculation of who won't make it, I felt a thread about who we want to make it is in order
Professor X - '92
Cyclops - 616 (certainly the most interesting)
Beast - '92
Angel - Inferno (presuming it's the one most recent after after becoming Death/Archangel)
Ice-Man -
Jean - Inferno (pre-Madelyne absorbion to be more precise)
Wolverine - Old Man Logan ('92 Logan is great, but doesn't offer much new)
Storm - '92 (any version post meeting Gambit but pre marrying T'Challa will do)
Banshee - timedisplaced version in X-Tinction Agenda (only Banshee around)
Nightcrawler - any, really.
Colossus - 616 (don't want to go back to a Colossus that sees Magik as an innocent snowflake again)
Rogue - AvX (up for the debate, but this one at least has full control of her powers)
Psylocke - 616 or AvX (they only made her a TK/TP recently, and any earlier version will probably develop those powers anyway)
Jubilee - '92
Gambit - current one's fine
Bishop - '92 or Civil War or AoA (dunno if he'll be in the former two)
New Mutants - X-Tinction Agenda
Magik - 616
Cable - Civil War
Emma Frost - Morrison's New X-Men
Rachel - 616 (any she exists in, really)
Havok - X-Tinction Agenda
Polaris - House of M
