I'm gonna be honest, I'd rather see Mortal Kombat win instead of Marvel vs. Capcom 3. MK9 had it's problems, but I enjoyed the game alot and I wish more people around me played it. Sadly it'll be a fighting game I never got any good at due to the lack of players in my area whom would rather play SF4 or MvC3.
Regardless, damn straight I'm voting for KOFXIII. I want to see the underdog win for once!
