Now that I can see much better, what's going on in the trailer . . . I noticed a few things.
Call me crazy, but I could swear one of the people walking in the background while Jet plays the Tron game, looks suspiciously like either Tom Goodman or a Siberian Guard from NOLF. I'm probably just seeing things, though.
Tanks will definitely be in the game. Probably as enemies or obstacles only, though.
Looks like Data Wraiths can take over ICPs? The purple ICPs are holding red discs.
Saved the best for last. There's a Pentium 4 ad in one of the game levels! Look for it in the scene where Jet spins the disc on his finger.
