Na, nintendo cycles for new consoles is always 5 to 6 years, that has been a rule of thumb since the NES, not to mention that iwata is just about to show us something about NX next year which means it wont be ready by then since Nintendo has never been ready to launch a concole inmediately after showing it off to public that same year and we also have to account that current gen has even to decline in sales and that nintendo must prepare a good arsenal of games made both in home and third party support
With the wii u faila nd iwata recognizing failing to deliver good launch games with wii u is unlikely they want to repeat the same mistake unless he wants to lose more inversionists.
Wii also had a lazy year like this before it was replaced and that year wanst enough to do things right, my bet is 2018 and the earliest of course would be 2017 which from my point of view is unlikely if they want to do things right
