Can't just be EA.
As far as I know we have no plans to release another WiiU game, and the one we've got coming out was a bit touch and go as well- the game was practically done, required some changes from the PS3/PC/360 version to make it work but the question was for the return on sales was it worth the marketing money to get the thing onto shelves.
Going forward our new renderer doesn't even support the WiiU hardware (nor the PS3/X360, that is being served by a legacy code base and will be phased out of production use by the middle of next year) and we have no plans to.
It also doesn't help that, compared to the other consoles, Nindendo's dev tools are pretty rubbish.. I honestly still don't know if they have a GPU debugger in existance...
