Geoff Keighley's made an announcement via his Twitter account regarding an all-new game from LucasArts. Unfortunately, that's all that it was: an announcement to an announcement.
LucasArts will announce a brand-new original game on this week's GTTV - with first footage. More details soon.
No idea what this new game could be, or for which platform it'll come out. Best to stay tuned so we can all find out, I guess.
Hmm... just a thought. Could it be, finally, a confirmation of the long-rumored XBLA title, Lucidity?
