Here’s a video pitting The Apprentice, from the upcoming Star Wars: The Force Unleashed videogame, against Yoda. Yoda is available from the beginning of the game, and the exclusive Star Wars character, in the Xbox 360 release of Soulcalibur IV. The Apprentice is unlocked once you complete the Arcade Mode with Yoda.
If you’re wondering if you’ll ever be able to play Darth Vader (PS3′s exclusive character) against Yoda, see a video here. That explains the little open square in the character selection screen (seen in the Apprentice Vs. Yoda video). Looks like Darth Vader may be locked with key on the disc, possibly to be available as a paid, or hopefully free, download. No official word on it yet.
