One publisher not publishing games for a console is not anything to worry about.
In this case, it is. Sports titles have always been casual titles that people buy every year and buy consoles just for them. Not to Forget that those titles atract millions of gamers and seeing the rise in popularity of the BF series, that is a serious blow to Wii U and 3DS too.
If you are one gamer who likes all or the majority os sports titles and enjoy shooters online, Wii U is no longer the platform for you. Why buy a Wii U when you can either buy a PS4 or X720 and get all those games without worries?
Unfortunately, EA has ignored Nintendo with the rise of Sony. Even Sega`s Dreamcast was ignored, despite being a hardcore console.
But this time, next year, EA is going to regret that decision. Wii U might not become the hardcore console of choice but i am positive that it will make strides to do what Wii and GC didn`t. And then... EA has to answer to investors.
