Honestly, that's fine by me. I don't really care for a lot of the stuff coming from major third parties anyway. Let Sony and MS fight over those. I've long since given up on any AAA devs, particularly from the west, supporting Nintendo platforms. Switch could sell 250 million, and most would still be just sitting on their hands going "derp, not powerful enough for our fantastic vision!" "deerp, we can't get Nintendo players to buy OUR games! Waaaah!"
For me, indies are the new version of third parties. Those are what are important, and Nintendo should focus on getting as many quality third party indies as they can to help fill in the gaps in between the major Nintnedo releases. And of course, there will still be the occasional major Japanese Squaresoft/Capcom/etc game sprinkled in, and an occasional Skyrim and Payday 2, or other ports. Coupled with all the Nintendo titles from both the home console and handheld pipelines, and the massive wave of indies, that's all Nintendo really needs at this point. Wii's success has proven you don't need strong AAA third party support. If these multi-million $ publishers are too short-sighted to figure out a way to tap into this rapidly growing market on the Switch and leave tons of money on the table, it's no skin off my back, and I don't believe off Nintendo's either. I have an Xbox One, and a decent PC for those anyway.
