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

I've never believed that that statement was meant to be literal, but more as a way of thinking.

Wii U was an enhanced version of Wii, and that brought in cons and pros. Some of the pros is that it allowed their devs to shorten their learning curve because they already knew some of the hardware they were working on.

I think that's the part they want to carry on, but not in the sense of NX being an enhanced Wii U but the NX handheld and NX home console sharing the same architecture (something also said by Iwata) but not the same hardware. Think of a handheld having a dual core CPU and a 16 "graphic cores" GPU and a home console with eight of the same CPU cores and 64 of the same "graphic cores", making the home console noticeably more powerful than the handheld but, because both have the same kind of hardware (but not the same number of them and thus power), devs will be able to go from working on one game for the handheld to a game for the home console and viceversa with little to no learning curve.

But that's just me speculating.

And the odds of NX using PowerPC are almost none. IBM moved on from those kind of cores and what they have now is great for servers but not great for a console.
