I think
Super Mario Galaxy 3 (or next EAD Tokyo 3D Mario)
Animal Crossing Next
Mario Kart 9
Are already in development for the next handheld. If they start now (circa summer 2014) and they have a good idea of their chipset and APIs, a lot of these games should be ready for the launch if its April-June 2016.
They did not plan for the Wii U or 3DS launches very smartly.
I'd probably go ahead and greenlight Hyrule Warriors 2 and Bayonetta 3 for the new portable too ... there's never a such thing as "too much" software, if you ever have that problem then you can just space out releases and delay a game if need be.
