Here the hackers go again
I try not to listen to roster leaks to often but after what happened with MVC3 I listening a little more.
http://shoryuken.com/content/rumor-full-mortal-kombat-9-roster-revealed-3855/ here's where I heard it.
They say the demo got hacked and they pulled the roster, might be believable. Ed Boon did say they had something special for the 360 users and I'm not seeing anything here. Maybe there are still some secrtets.
