People seem to have taken the idea of providing resources towards porting as suggesting that it would get people to buy the system "for FIFA" or "for COD."
That wasn't really the point.
The Wii U is essentially excluded from consideration by a large swathe of consumers because it lacks FIFA, and will now be even more so because it lacks COD. These, are for all intents and purposes, order qualifying criteria in the console market for a large/the largest market segment.
Does something like Bayonetta 2 really provide anything towards order qualifying or winning criteria to a significant market segment?
I think someone just answered no to either, and that's certainly a possible better alternative.
I'm not sure that it would help Nintendo, let me tell you a little story about my sister and her boyfriend:
They are huge Fifa fans and played Fifa on PC, but didn't want to buy a new PC. They had Xbox 360 controllers I gave to them as a present and played the games with these controllers. Then, they decided, to buy a console to play the next Fifa. My sister called me and asked me about the PS3, what to take into consideration, where it can be bought for cheap. I told her all this and then she asked about using the 360 controllers and complained that she couldn't use the way superior Xbox 360 controller (from her and her boyfriend's perspective. I share this sentiment, but I acknowledge that not everyone agrees with us on that) then anymore. When I told her, she could just get a 360, reuse the controllers and pay a bit less for that system than for the PS3, she was totally surprised and asked "But how would I play Fifa then?". My answer, that Fifa is available for Xbox 360, too, was almost shocking to her and her boyfriend. And she's not the only casual (though she's buying Fifa every year at launch and plays it for several hours every week, so maybe not too casual?) thinking this way.
Mind you, I'm from Germany, in UK this probably is less common. But I think that this kind of sentiment hits Nintendo way harder, also including games like CoD on top of Fifa, even when they were in fact available for the Nintendo systems.
