Probably another strong 7 titles for the Wii U, (like Animal Crossing and Metroid)
I don't see a whole lot of strong 3DS titles, but there will definitely be more games for the 3DS.

Yep, N64/GC/Wii each had 4 strong years of support then the 5th/6th year really bare with the exception of a couple titles. Based on that, I would say 2016 will be the last year of solid support for Wii U from Nintendo. Here are the North American retail releases of 1st/2nd party Wii U games.

2013-Lego City Undercover, Game & Wario, Pikmin 3, New Super Luigi U, Wonderful 101, The Legend of Zelda: The Wind Waker HD, Wii Party U, Mario & Sonic: Sochi 2014 Olympic Winter Games, Super Mario 3D World

2014-Wii Fit U, Donkey Kong Country: Tropical Freeze, Mario Kart 8, Wii Sports Club, Hyrule Warriors, Bayonetta 2, Super Smash Bros. for Wii U, Captain Toad: Treasure Tracker, NES Remix Pack

2015-Kirby and the Rainbow Curse, Mario Party 10, Splatoon, Yoshi's Woolly World, Xenoblade Chronicles X, Mario Maker, Devil's Third, Fatal Frame V: Oracle of the Sodden Raven, Star Fox

9 titles each in 2013/2014/2015 so let's assume 2016 has the same amount.

2016-Shin Megami Tensei × Fire Emblem, Pokken Fighters, Paper Mario, Metroid Prime, Animal Crossing, Diddy Kong Racing, Punch-Out!, Super Mario Sunshine HD, Legend of Zelda

I could see something like that next year and maybe 2-3 more 1st/2nd party retail titles in 2017 and a successor in late 2017.

This - at least as far as the WiiU goes

As for the poll question:

there are alot of variables not mentioned in the question- for starters does this include games currently being developed that we know about and or do not know about?

Does a Zelda U or Metroid U count the same as a SNES Remix 3, 4 and 5-- does it include 2nd party games funded and or partialy funded by Nintendo 

Probably best to have 2 separate questions re the Wii u and 3DS

few more for 3DS and a lot for Wii U Im basing this off my thoughts that 3DS/Wii U successors in 2017/18
