A remake of Jedi Knight? Hmm, I can't really see the benefit in that. IMO the Sith engine has aged extremly well, and with the model and texture upgrades available (produced by the modding community), the game still looks good and is giving me tons of fun (I happen to be playing it just now for the first time, and it is really a blast).
If they make a new game, they should go all the way and come up with a nice new story. Actually, thinking of the mess that TFU's story is, they'd probably better have someone else do it (oh, and thank you very much for ruining that part of the timeline for me, LucasArts).
