Regarding the talks about the NX....I think a few of its future tittles (Zelda, Metroid Prime Sequel, EAD Mario tittle, Diddy Kong Racing 2, ect) have to be cross-platform with Wii U, as not only did these games start on Wii U, but people would be pissed that a significant chunk of the Wii U's heavy hitters migrated to the NX and that they have to buy a whole new platform just to play them.
A bad move on the level of the 'surprise' announcement of the Saturn releasing the moment it was announced and the CD/32X add-ons; moves that alienate your core fan base and flat out confuse consumers.
But the thing is that Nintendo is in a 'do or die' position; they need third party support and the Wii U isn't viable for the console for third party support (the excuses of lack of install base and lack of horse power for big games (KH3, FFXV, ect) come to mind
). So, if they want that support, they have to move on with stronger hardware to support future tittles. And.....I think it isn't a bad move gearing up for the launch now so that way there will be no software droughts like their was for the Wii U's first year.
And to be honest, the line up for the next year is very solid in comparison to the GameCube and Wii around this time period:
-Mario Maker in Sept.
-Star Fox Zero in the fall
-Yoshi's Wooly World in Oct.
-Xenoblade X for Dec.
-Devils Third and Fatal Frame coming in the fall (don't know the dates on those sadly :l)
-Mario Tennis for this fall
-Mario Party Cl....I mean Aninmal Crossing Amiibo Party coming in the fall
-SMTxFE coming in 2016
-Pokken's console debut coming to Wii U first in 2016
-Zelda coming in 2016
Those releases alongside remasters for a few GC and 3DS tittles (Mario Sunshine, KI: Uprising, Paper Mario TTYD and Luigi's Mansion 2: Dark Moon) could create a strong line up for the final year of the Wii U's life.
That alongside a number of the NX's launch tittles being playable on Wii U (Zelda coming to Wii U first, Metroid Prime Sequel also coming to Wii U after the NX version and maybe even the EAD Mario coming cross-platform for Wii U and NX) and maybe even having a cross-buy system where your Wii U tittles automatically work on NX through the new Nintendo Account system coming could foster good will for Wii U owners for the 'rushed' push on NX.
The reality is that Nintendo is doing a better job supporting a 'failing' console then Sony ever did with the Vita and unlike the Vita, Nintendo can't just drop it, so they did a ton for the system across 2013-2015. If I owned a Wii U, I would be happy with its line-up of software and mirroring Sony's output on the Vita, we got a mix of solid new entries in franchises and new IP's altogether. Nintendo did a strong job with the system and we still have games coming.
It sucks that the future of the Wii U is now looming over the platform again after such a strong year between 2014 and early 2015, but great stuff is still coming and I have hope Nintendo will do good for loyal fans who got a Wii U
