gonna be a long time considering they are working on Injustice now.
Before that game was announced and when I thought MK10 was around the corner, I too thought it would be best just to wait for MK10 instead of having more DLC. But now I feel they have kinda abandoned a potentially huge game and missed their opprotunity to expand it. I think we should get more now that we are waiting for MK10.
This or they should start showing MK10.
