With EA all but casting a vote of no confidence in Wii U, the third-party software picture is going to look awfully barren. We can't even really compare it to Gamecube because key third-party publishers like Midway, Acclaim, and THQ who supported GCN are all gone. Activision sticks around, and Ubisoft execs are trying to say the right things. Capcom is supporting Wii U somewhat, but Konami support is inconsistent... as is support from Square-Enix.
I'm trying to imagine what Wii U looks like with no sports games. What if (though unlikely) EA doesn't port at least Madden and FIFA to Wii U? No football, maybe soccer if Konami ports its own game, no hockey, no college football, and golf is up in the air. Nintendo has no answers for this; Mario sports games won't attract the sports game crowd. No sports games would pretty much guarantee that a fair number of consumers won't even look twice at Wii U and instead choose between Durango and PS4.
This is when a real leader-- which Iwata isn't, apparently-- gets a meeting with EA and pitches a financial deal to keep the publisher on-board, mitigating low ROI and other financial risk by EA in order to fill a need in the Wii U library. This won't happen, I don't think, and Nintendo will find out how a lack of EA titles will damn its new console to a has-been or never-was before it even had a chance to succeed.
