Because of how great the Wii was I bought the Wii U year one. Something I have not done in three generations.
As of right now, it will not happen with their next console.
I'd like to say no, and for Nintendo it will probabally stay no, but it has caused me to re-evaluate when I purchase a console in general.
I bought and paid for a PS4 (pre-order) months before it came out, and as I saw nothing for the system (including lacking backwards compatibility for my few PS3 games) I cancelled it, got a second Wii U for a different room in the house.
So what is available is going to color my opinion on anything, and I am a primarily PC/Nintendo gamer, so it is probabally worse for any other system since they offer me next to nothing.
