Tron Legacy Game Confirmed?

Latino Review reports a confirmation of a Tron Legacy game to tie-in with the upcoming Tron movie sequel, saying this was confirmed at this weekend's Disney D23 Expo by producer Steven Lisberger. He told them this in spite of his indications that this might not be something he should be discussing publically, but it's hard to imagine a movie that takes place within a video game without a video game tie-in.
