I think your pricing is high for what they system costs these days. Wii U could've been a huge hit had they made it a bit more powerful (didn't have to be on par with ps4 or x1) and dropped the gamepad. They couldn't explain why it was needed or why it was innovative, Nintendoland sucked imo and at the very least was a FAR cry from Wii Sports in terms of a word of mouth system seller, and just as many predicted it became a tack-on feature, much more quickly than motion controls did for the Wii by the way. Hell DKC doesn't even show the game on both tv and gamepad at once. Its a totally useless feature imo and hinders the comfort of using a controller. I'm glad I finally bought a nyko pro controller when it was on sale last week.
This being said, I love the system. I really do, the 9 games I have are all awesome. But if Nintendo put these games on X1 and PS4 nobody would ever have a reason to come back to Nintendo. If they go third party, they're making their bed. Is that a bad thing? Depends who you ask but possibly not. Either way, I think there are too many games in development for the Wii U that are coming out in the next 2 years to just scrap the console. It IS selling, it's not like HD DVD here.
I'm not particularly interested in Smash Bros. but the X RPG, Zelda U and HOPEFULLY something Metroid comes along soon. Until then, I still haven't picked up DKC or Lego City. Plenty to play if you give the system a chance.
My one and only argument to what you are saying is that Nintendo did show, when the GamePad was first shown, how it added value to your games. The problem is, THEY not even once did any of those examples in a game.
They need to, and fast. Within a year I hope we see some of those original ideas fleshed out in a game.
