I currently own a Xbox360 with a street fighter IV gamepad to make fighting games a lot more comfortable to play and I want to purchase Injustice: Gods Among Us. I also want to get a Wii U in the future (probably Holiday 2013 or Summer 2013 if needed) and there is a deal currently for the game on both systems on a great price that I'm not sure which system to get it on. Should I buy it now for the 360 or should I buy the Wii U version now and wait until I get a Wii U? Is there any significant differences of the two that I should be aware of?
