Probably due to licensing issues I'd imagine.
Activision own Crash and Spyro now and I believe Eidos or Square Enix own Lara (not 100% certain about her, but it was never Sony). They probably didn't want to give Sony the rights.
I'm disappointed Crash isn't in it, but I'm still interested in the game. I'm just hoping there's a reasonable amount of single player content.
