Who knows what that means as far as what will actually be fixed, but if they can improve the online play a bit and get rid of that unpause/can't move glitch, I'll be a bit more satisfied with the game.

I am going to wait a few months till this game gets all fixed, If you need me I'll be playing MK9..

I don't really play online with it, but im glad to hear it's getting fixed.

When even the hardest of the hardcore Mortal Kombat fans are disappointed, you know your game has issues.
