The Force Unleashed site is up. Go take a look if you want.
If you haven't already, you'll need to watch the trailer and then check out this Penny-Arcade strip.
UPDATE: Of course the main draw in the new site is 'The TFU Experience' (they really haven't seen Spaced, have they?) video, which shows off the game on the other non-LucasArts developed platforms. Prepare to seeth with rage when Haden Blackman says "we wanted the game on as many platforms as possible" and then forgets to mention the PC in any way.
Anyway though, there seem to be cool exclusive features on every platform, as Glo_kidd suggests is probably to get people to buy more than one copy of the game.
PSP version - historical fights from the movies.
PS2 version - Jedi Trials mission.
Wii version - incredibly cool control system that seems to work just as we'd hoped.
DS Version - A handheld console you actually want to own.
360/PS3 version - Full LucasArts-developed Euphoria-powered version.
PC version - The chance to play through Jedi Knight, TIE Fighter, KOTOR or Empire At War again.
