Mario is the last Nintendo franchise I care about. I got a WiiU 2 Boxing Days ago in anticipation of the Mario games - but they underwhelmed me. The first 2 platformers were ok (sorry, I'm not treating the Luigi treatment as it's own game) and Mario Kart 8 was ok, but nothing fantastic. I didn't bother with Super Smash or Mario Maker as I don't care for the genres.
I'm not sure I'm getting an NX. I might be tired of Mario to buy a console for. Although, if they go 3rd party for my Xbox One - I'd probably be all over a Mario platformer.
