I'm happy with it based on the controller alone. Wii-U's tablet controller was uncomfortable beyond belief, and the pro was nearly unplayable (for me) because the face buttons were where a second analog stick should be (or rather
is on every other controller with two analog sticks), so I was constantly pressing buttons I wasn't meaning to press because muscle memory (gained over how ever many years) told me that a particular face button should be in a particular place based on the positioning of my hand. The wii-u's pro design seemed to be change for the sake of change (without thought put into whether or not that change was actually good), so long rant over, freaking a useable controller this time around, nice.
All that aside, I don't care much for Nintendo first party games at all anymore. They haven't made a Metroid title I was interested in since Zero Mission came out in 2004, and the next title (if there is one) will likely be prime. Never was a fan of Mario all that much, 3D or otherwise. Only liked the first Star Fox on SNES. F-Zero is dead in the water for some reason (and that reason is that good racing games don't sell). I've grown out of Zelda (not because I think it's childish) and no longer admire its aesthetic design nor do I enjoy the gameplay.
Their games used to be interesting, back when the GameCube was their newest console (and far reaching back to the NES and Arcade), but ever since the Wii, it's been an endless rehash of safe and familiar trends. Nintendo doesn't make games anymore -- and until they do, I have little interest in whatever console they're trying to push. At least this time around the gimmick is practical.
