Wouldn't really surprise me.
The main EAD Tokyo team that did Super Mario 3D World hasn't really released a game since November 2013. A small off shoot of that team did Captain Toad, but even they have not been heard from in 2 years.
Summer 2017 (lets say) will be 3 1/2 years since Mario 3D World ... they are more than overdue for a new Mario platformer.
Zelda is a given because they borrowed it from the Wii U.
Pokemon ... didn't they say the new game (Sun/Moon) has HD assets? Probably so they could do a quick port to the NX.
