Wii U's not going to have Tomb Raider the Definitive Version or Grand Theft Auto V The Definitive Version ( which will be announced in the near future ) or Titanfall Game of the Year Edition ( if it warrants one which will be coming to Playstation 4 just like Bioshock did in the 7th Gen ) or Grand Theft Auto VI and many other third party games which will be coming to PS4 but not to Wii U.
Now it's true that people still love Nintendo's franchises but with each release in the same old series people just get a little more tired of them while new franchises ( ie. developed on the other consoles within the past few years continue to grow in popularity ) while Nintendo hasn't come up with a new core franchise in decades and the casuals aren't going to buy their casual games in the same numbers that they did on the Wii.
To make a long story short, with some hefty price cuts and by appealing to the kiddy demographic, Nintendo could pull it off, but I hope they don't.
I like how u say Nintendo releases the same old series while 2/3 of ur examples for other consoles belong to 15-20 year old franchises and are updated ports lol
"Uncharted," "God of War," and "The Last of Us" on PS4 and even "Halo" on Xbox aren't 15 to 20 years old. Mario, Donkey Kong, Zelda, Samus, Mega Man, they were all around before I could drive a car and that was a long time ago. Where's Nintendo's hard core adventurer hanging out with ladies with fine asses like Nathan Drake, or their Kratos with all of his violent and bloody struggles and hot sexual encounters?
