It's not so Nintedoooom, I'm saying I don't think these two platforms can really hold the fort for Nintendo until 2017.
3DS is only holding relatively OK because it has a new hardware revision this year whereas last year they didn't, but the YoY impact of that lessens the further out from release you get on that. Even there though YoY declines are starting to become noticable, this time next year we likely are talking about 3DS sales that in the 20ks/week which is not really where you want to be if you're Nintendo.
Wii U obvioulsy is just a lost cause entirely in Japan. Barring Splatoon becoming the new Pokemon, Wii U is just finished there. Wii U should be UP not down after MK8/Smash etc. too, there has a base line decline rather than increase (even just a minor one) which is particularily sad.
Assuming a year from now (March 2016) we're in the 22k-28k/week for 3DS (combined) and Wii U is in that ugly 5k-6k/week range, which I think is a fairly reasonable projection .... can they really just hold that until 2017? I don't see it.
From a Japan POV, NX needs to be out by the second half of 2016, maybe even sooner to be honest.
