why would you listen to the movie because of a simple character ?
normally when you look at a movie its for the whole concept not for one single character !

anyway...
jubilee IS in the second movie... in the last news at last !
COLOSUS is there too, but like bobby was in the first one, he will be a background char, not an active one !
PYRO, ICEMAN, ROGUE, NIGHTCRAWLER, CYCLOPS, MAGNETO, SABERTOOTH, MYSTIQUE, TOAD, LADY DEATHSTRIKE, WOLVERINE, JEAN GREY and storm will all be there !

they are all against the famous ANTI-MUTANT group called "THE FRIENDS OF HUMANITY" led by MR CREED (yeah, that's SABERTOOTH son) its a drastic measure group that uses drastic weapons against the mutants... its the only HUMAN group that give X-MENs big problems when they are around !

for SABERTOOTH, TOAD, MYSTIQUE ...
like MCKELLAN said on his site...
when they signed up for the contract, it was obvious that they would also all be doing the second part too ! so yeah the whole crew of the first movie is still there !
