Nintendo fans are never going to be satisfied with the tail end of the Wii U anyway.
Zelda: Skyward Sword came out late in the Wii's life cycle, so did other games like Xenoblade, but most Nintendo fans still look upon the late Wii cycle as garbage.
The tail end of the GameCube sucked ass too. The N64 was quite mediocre post Perfect Dark too.
It's just how it goes. You guys aren't going to be happy with the late cycle of the Wii U, and Zelda isn't going to change that (Skyward Sword didn't for the Wii and obviously Twilight Princess didn't for the GameCube).
It isn't like Zelda will come out on Wii U and magically every Nintendo fan will remember the Wii U as some kind of massive success. That ship sailed away a long, long time ago.
The Wii U's legacy is pretty much cemented. If the NX is a success then it'll shift to "well the Wii U was a turd, but Nintendo learned their lesson with the NX!" and if the NX is a flop forcing Nintendo likely out of the hardware business, then Wii U will be looked back upon as the Sega Saturn (with NX playing the role of the Dreamcast). Either way it's lose-lose for Wii U. It will never be remembered as a "great Nintendo console" no matter what Nintendo realistically does at this point, if they throw a ton of resources at it, thus forcing a barren NX start, then even that will be looked back upon as a massive mistake "why was Nintendo so stupid to keep supporting the Wii U when no one was buying it, that caused the NX to be delayed and other big franchises to come late in the console cycle and basically screwed the NX generation up too".
