Yes, Colossus is in X2 in a brief cameo role ala Iceman in the first X-Men. So if they follow the Iceman trend, they'll probably give him a bigger part in the third movie. There is a shot of Colossus going into metal form in one of the trailers.

Beast is also supposed to have a small cameo in X2, but before the blue fur. He was always one of my favorites, but I like him better with the fur, so perhaps we'll be lucky enough to see him that way in the third movie.

Word around the campfire is that one of the X-Men is going to die in the third movie. I know who it is, but I won't spoil it for you others.

Everyone really wants to see Gambit (not one of my favorites, though he was when I was younger), so maybe he'll be in the third.
