Nintendo should have 3rd party collaboration if Nintendo's own dev team are mostly focusing on NX. And those 3rd party collaboration deals should already started development for the games slated for late 2016 and the whole 2017.
We all know as of right now, there aren't any big games slated for late 2016 and 2017 besides Zelda U.
For me, i just normally look Wii games and buy older games.
