The only way I can see the NX succeeding is this

I've considered this but only in a a situation where the NX "dedicated" home console does not arrive til 2018.

So essentially what we're receiving in 2016, is a powerful, dockable handheld that will phase out the Wii U. Going forward it's fine that Nintendo ports all games across both systems but how is BC achieved without the handheld also being Power PC? (a big no, no!)

Ultimately what makes the most sense is that Nintendo abandon the Wii U and 3DS at the same time, instead of trying to shape a new system after the Wii U. The fear of Nintendo's brand being damaged by them ending the Wii U's life 1 year short of 5 years is ultimately nonsensical, Xbox suffered the same fate and no one cared with 360. The damage from Wii U has already been done and it's not from a 4 year life cycle, it's from a lack of software on a yearly basis. Something that will not be fixed by giving the Wii U 1 extra year of life.
