Hmm been thinking about this quite a bit actually.
1. Price drop. The Wii U is too damn expensive given the lack of content/ quality of the hardware. Honestly, It needs $100 shaved if it wants to be even viable.
2. New Metroid. It's been long enough. We've had like 20 mario games since the last metroid game.
3. More 'X', looks awesome. I want a release date and more gameplay shown.
4. Some sort of unified network. Enough of the friend code bs.
5. New IP? I don't think nintendo has made a new series since like..well ever.
I sense a lot of negativity and see a lot of misinformation/peer-perspectives...
1. No offense, but #1 is wrong on so many levels. There is no lack of content, as there are plenty of titles, both first party and indie, to choose from that the list would be insanely large. I'd love to make that list, but its getting tiresome. If a game doesn't "appeal" to you, it doesn't mean it doesn't exist. Also, asking for $100 shaved tells me you probably don't own one, because there is no lack of quality in the hardware at all, especially when you recognize that the Gamepad has a built in camera, built in microphone, built in sensor bar, built in stereo speakers, headphone jack, and all the usual fixings of rumble and gyroscope feedback, along with having the touch screen and lagless video streaming. Mario Kart 8 also proves the hardware in the console itself is plenty capable.
2. We have not had 20 Mario games since the last Metroid... I assume you were being sarcastic and dramatic, but come on, is this one even a valid point?
3. I can agree with that.
4. Friend codes? What friend codes? I'm sure you don't own a Wii U at this point, because there are no friend codes, lol
5. The Wonderful 101 was entirely funded and published by Nintendo. That's a new IP, yet no one wants to buy it. I can't blame Nintendo for sticking to the tried-and-true, because when they DO venture into a new IP with their money, people just ignore it. The fact that you said "well ever" also tells me you have not really looked into Nintendo's library. Gems like "Eternal Darkness" also came from Nintendo's coffers of money. In fact, if you want to limit it to Nintendo-developed IPs, the Wii series of games (Wii Sports, Wii Fit, etc.) are new IPs started in the Wii era. You may not like them or prefer them, but that doesn't mean they don't exist.
I feel if you're going to be negative about the Wii U, I can respect that, but I don't like seeing it littered with misinformation. If you don't like the Wii U and don't see the value in it, that's fine, don't buy one. But some of the things you're stating like they're facts are not even close!
