It looks like Yoda and Darth Vader are finally working together. You see, the two Jedi masters have managed to help push 2 million copies of Soul Calibur IV onto the gaming populace. The number accounts for both the Xbox 360 and Playstation 3 version of the game. We're curious to see which version sold more copies. No, not because we want the Xbox 360 version to succeed, but because we want some new nerd ammunition for the next time we get into the Darth Vader vs Yoda conversation.
