Here is a article I found, it mainly talks about the voice acting in the game.
"Joining Wilde and Boxleitner as voices in the TRON: Evolution video games will be Jensen Ackles (Gibson), James Frain, John Glover (Abraxas), Nolan North (Behemoth, Sentries and Blaze), Kari Wahlgren (Radia), Robin Atkin Downes (Kalev), Terrence A. Carson (Calchas), and Fred Tatasciore (Kevin Flynn, Clu and Bosh). Diane Michelle, Yuri Lowenthal, and Laura Bailey also provide voice audio for the game."

I'm glad to see some great names on this list, Wilde, Boxleitner, Frain, and North. But a little upset that Jeff Bridges voice won't be showing up on the game. Oh well, Tatasciore has a really close voice to Jeff Bridges.
