People who think Nintendo can seriously support the Wii U on top of even just a portable NX are in for a rude awakening.
They can't even finish a Star Fox game that looks this low budget anywhere near on time. At E3 2014, Miyamoto said this game would be ready in about a year, it will be over a year late.
Which personally I'm fine with, but the idea that they can support two high-end platforms going forward when virtually every single Wii U game they've published has encountered significant delays ... c'mon guys, the writing is not only on the wall here it's in bright neon pink.
NX has to significantly alter the Nintendo platform structure, they simply cannot continue like this, if they are choking on Wii U development, they are going to absolutely die with a PS4 level console, which is why I suggest simply letting the "big box" home console NX handle big third party ports while Nintendo games should just be (basically) Wii U-complexity engines just souped up to 1080P + 60 fps + 4X AA.
Things like Star Fox and Yoshi's Wooly World take forever, but really epic scale HD titles like Xenoblade X are ridiculous (3 1/2+ years of development) and Zelda U (will be nearing what ... 4-5 years in development this fall?).
