I have owned literally every single Nintendo console (at launch) except the Wii U. Still don't have one, and no interest in getting one. And here is why:
Super Mario 3D World - This looks interesting and all, but having played through every single mario side scroller before it along with every 3D mario platformer before, does it really do anything excitingly new that I should spend $300 for it? I can go back and play galaxy 1 or 2 or the NSMB on my Wii and have an equally satisfying experience.
It's very different to Galaxy and NSMB... do a little more research. It's more akin to 3D Land.
Wind Waker HD - Played the hell out of this on Gamecube. Looks great, and would be a must own if I was convinced to buy a Wii U, however, a game I already own is not a motivator to buy a new console.
Fair enough
Pikmin 3 - Played the hell out of Pikmin 1 and 2. Why do I need this game? What does it do that is so much better than the previous ones? (granted, it looks a bit better).
Like every other sequel on the videogame industry, new content.
DK Tropical Freeze - Read Pikmin 3, but change it out for every other console DK.
Emm, it's only comparable to DKCR, it doesn't play or look anything like the DKC trilogy of the SNES. Do more research.
Mario Kart 8 - Read Pikmin 3, but change it out for every other Mario Kart.
Read my pikmin 3 answer, new content, freshened up look, and solid online play.
Hyrule Warriors - I don't like Dynasty Warriors, so why would I like Dynasty Warriors dressed up as something else.
Haven't played this enough, but it has a lot of "nintendo polish", it's a good mixup.
New Super Mario Bros U - See Super Mario 3D World
totally different styles, do more research
Xenoblade Chronicles X, The Legend of Zelda - These are the only two games that look interesting to me, and there isn't even a release date or more info for Zelda.
Nintendo just keeps rehashing the same franchises, and while they are well made and play well, there is nothing ambitious or new about any of them. Likewise, since Nintendo doesn't really rely on story driven games, I don't even have the minor interest of playing a game to see 'what happens next'.
There is literally no downside for me skipping the Wii U, except for maybe Zelda. When the next Nintendo console comes out, guess what? It will have Smash, Mario Kart, tons of Mario games, etc and they will be just as unambitious and sameish. I don't mean to harp on them because I really do love Nintendo, but if I've played 6 or 7 Mario Kart games, why do I need to pay $300 to play it again if there isn't really anything groundbreaking in it?
Based on your reasoning, the console to own in 2014 is the Xbox 360, the Wii, or the PS3.
