I don't doubt good games, but I really can't put support behind yet another console where the only quality titles are first party and are drip fed over the course of the console's lifespan.
The last time anyone bought a Nintendo console with a good balance between third party and first party in mind, processors couldn't go over 64 bits. You buy Nintendo consoles for the same reason you used to buy Sega consoles. To play first party games.
While the WiiU was a botched return to core gaming in more ways than one (Main one being the crappy support overall of established Nintendo series), it's still a much more distinct console than the third party copy paste, echo chamber battle that the Xbone and PS4 are having. Everyone's still starving for those exclusives and those console purchases are almost completely driven by brand loyalty. It's insane. At least with the WiiU you're getting mostly what you want, sequels to some of the Ninty franchises you love and new IPs, some of them pretty shitty (Devil's Third) and others pretty amazing (Splatoon). And for all the negativity and shitty execution, I'll always cherish my WiiU for the sole reason of Nintendo spearheading the Bayonetta sequel, something that Sega wasn't willing to fork the cash for, which is pretty ironic since Bayo 2 still presented a parade of Sega homages after Bayo 1 which was almost a love letter to old Sega games.
Anyway, they're teasing Super Mario Galaxy 3 for the NX and that shit alone would be enough for me to consider a purchase. Pinnacle of 3D platforming, man. 3D World was nice but ultimately disappointing compared to the previous Galaxy games.
