Eh, they should know better than to give so many concessions to one region so often, leaving out the others. It's their job to know the fanbase, and 2 of the first things anyone would learn about it is that each Gen is someone's favorite, and some of their fans didn't start on Gen 1. They're practically alienating a lot of people by ignoring the wishes of roughly 4 to 5/6 of them, and the discontent isn't a secret at all. It's odd for Nintendo not to listen to fans for new release input, and given the timing, I'd almost guess it had something to do with Satoru Iwata suddenly passing last year. They lost sight somewhere, and they preferred to look at what worked in the past, instead of putting in the legwork to listen. They lost important leadership, and with him gone, I expect this to be the first of many slip-ups from them for at least another year.
But gaming entities undergoing fiscal problems sometimes resort to making deals with 3'rd parties, so crossovers might be more likely.
