I expect this one to follow the movie a lot more closely than the Nintendo 64 game did, and be much more story-driven. That's the vibe I got from the trailer. There likely won't be levels that Bond didn't visit in the movie, such as Siberia and the Silo level, and the two temple bonus levels. From the looks of it, they're going to play this up as a re-imagining of the N64 game when it really isn't, and appeal to retro fans. I'll bet most of the game is completely different, but in that trailer they showed a few key movie points that were present in the N64 game to entice fans.
That's my take from what little we know.
