What does EA expect Nintendo to do for them exactly? Did MS or Sony do something magical to make people buy more EA games on their consoles? The Wii was a flop because anyone looking for serious gaming was going to do it on a better console, and all the 65 year old women who bought one only bought it for Wii Sports.
And enough about DX11. The WiiU graphics are a quantum leap above the overclocked dinosaur that is the Wii. That is the most important thing. I'm sure PS4 and Xbox720 will be better, but as long as they are all out of the dark ages, cross platform development will be easier and the differences, while possibly noticeable, won't be night and day as they are now.
