Kind of like Soulcaliber 2 with Link for the Gamecube version, Heihachi Mishima (from Tekken) for the PS2 version, and Spawn for the Xbox version.
Only this time it's Vader for the PS3 and Yoda for the 360, with Vader's Secret Apprentice from The Force Unleashed on both.
I just can't believe they put them on the box. It'd be like Tony Hawk 3 having Darth Maul and Wolverine on the cover...
