Currently...because you never know when it's going to change.
Colussus - Dead
[b]Magneto[b] - Dead
Wolverine - he's now not the only "Weapon", X means 10, so there's more and it turns out he was born in the late 1800's
Iceman - is also starting his second mutation.
Cyclops - is having a psychic affair with the White Queen, and is going through some depression (yes, even more so)
Nightcrawler - is now a priest and is trying to find out if his mom is truly Mystique
Jean Grey - yes, her Telekinesis is phenomenonially more powerful and yes she is slowly coming to terms with the Pheonix Force.
Angel - has taken control of his company and is having a fling with Husk (18-19 yo?), and yes, can heal others now.
Beast - looks more like a tiger now
Prof X - yes, healed by Xorn...and seems to be more cynical, public, proactive and a bit more ruthless, less idealistic.
Havok - was in a coma, came out of it, almost married Polaris (who turned out to be a murderer), and fell for his nurse.
NorthStar - of AlphaFlight fame is now teaching at the school and is getting involved more.
White Queen - is now a good guy, and now is being revealed about her past (she got plastic surgery)
Juggernaut - is now staying with the Xmen, and is trying to be a good guy
(not nice, but good...working out issues with himself & his half-brother Prof X)
Storm, Rogue, Cannonball, Sage & Bishop are now in a separate more public group (Xtreme Xmen)
(they actually got acknowledged by the general public for saving the world...can you believe it after all this time?)
I forget where
Gambit is but I think he lost his powers...for now at least.
BTW, the Beast gay thing was in "Ultimate Xmen", this is an alternative universe
The titles that represent the "real" time line & mostly the main teams are:
The Uncanny Xmen
New Xmen
X-treme Xmen
Other Teams:
X-force
X-factor
Same Timeline:
Wolverine
AlphaFlight
Good titles, but different universes
Ultimate Xmen
Exiles
Old titles that are gone:
Cable, Generation X, X-man, New Mutants & Mutant X
Villians that haven't shown in a bit:
Sinister & Apocalypse (thank god, I hate them)
Of course, each Xman has their own mini-series in the meantime...White Queen is the current one
Now this is cool because it tells her origins.
This is what's coming at us...
