Opinion: As earlier NX releases, as bigger are the chances it wont be what your waiting for.

You have to keep in mind that even if NX (home console) is released in 2017... it would be launched just some months after 2016 ending. I mean, they can't wait until Spring/Autumn/Winter 2017 because they just don't have games to support Wii U that long.

So, I think is irrelevant in which year the consola is launch, because the difference of time will be three-four months AT MOST.
