Lost?

I'm barely retaining interest in Lost - though last week's episode was a return to moving-the-bloody-plot-along-at-last form - but am quietly looking forward to the forthcoming game. Due out on 360, PS3 and PC towards the end of the year there is little info around on what the game will actually be like. And maybe that's why I'm interested. Could it be a character-driven adventure set on the Far Cry island? Will the polar bear get involved? Or will it be another 24 - ie all the official sound effects and voiceovers but not much game?
