Well, the characters look more squat, and they changed Ben's bike, but I think it's looking good so far. But everything is in 3D graphics, even the environments, so you'll be wandering around just like you would in Tomb Raider, apparently.
The bad guys look pretty cool, though I hope they're not planning on leaving out the Cave Fish. Check Gamespot for a lot of good info, or LucasArts of course.
I'm really hoping they give us SOMETHING about the new S&M game. ANYTHING.
