Here's a video of the Wii Battle grids game. I don't know if it's new or not, but it was new to me and showed a brief moment of what looked like 1st person on the lightcycles! It's not a very practicle way to play (if the lightcycles in Tron 2.0 are any indication) but I really like the option.
It also looks like there might be parts of the story mode where you walk around talking to characters? I'm not sure but it looks like it could be a slightly deeper and more interesting game than I thought (though I was interested enough to finally get a Wii just to play this game. We'd been talking about getting one for a while, but anticipating this game definitely put me over the edge. The Wii actually arrived in the mail just this morning 15 minutes before i had to leave for work. Been looking forward to trying it out all day
Also, here's a series of videos of some of various games. In particular they show the Jai-alai game from the first movie!
(took me forever to find these again. for some reason they are filed un "Tron 2" :/
