Still better than Metroid Snap.

Lmao at people donplaying spinoffs. Here are some below.

Super smash brothers
Mario Kart
Donkey Kong Country
Diddy Kong Racing.
Yoshis Island
Paper Mario
Luigis Mansion
Just Dance (major success but i dont like it)
Forza Horizon

Lets just judge the games as they come mmmkay?

It seems they havent learned anything. And making a proper open world game seems too much for them (Zelda U). Well. If they keep being deaf to market needs and keeps spin offing major franchises then none will buy Nintendo system. I will buy Wii U for Zelda when the system is $100.

Agreed.

More shock awaits in future. IMO they havent learned anything. And HD development in next gen might prove fatal in they keep being as they are now.

IMO Nintendo has quite a lot of games they could bring out for Wii U, like a big Super Mario game on par with 64 and Galaxy (I know people have said that 3D Land is like that, but I don't think it went far enough, or had the same level of wow factor), they could bring back Blast Corps, make a big screen edition of Pilot Wings.
An open world Pokemon game would no doubt be a system seller and greatly appeal to the target audience of the system. Pokemon will no doubt move a lot of Amiibo figures and big game like that could have several DLC expansions or new releases like the handheld games, adding new Pokemon, sections to the world, etc.
I always thought a Kingdom Hearts style adventure, with a new lead character that interacts with Nintendo's characters would be great, basically a big RPG and huge fantasy world set in a complete Nintendo universe would be a huge system seller.

Bringing back Wave Race would be awesome too IMO.

Maybe put some more focus on franchises that aren't as well covered like F-Zero, Metroid, Starfox.

These comments from Miyamoto could mean that Nintendo had to build game engines that are more flexible for the current gen hardware, now they may have those, so that would drastically speed up the development process, given how automated a lot of these engines are now and Nintendo must re-use a lot of the same assets across the Smash, MK and many of their franchises, which speeds things up too.

It's really not that hard for Nintendo to have a lot of content that could move units, they just need to plan better, start development of a lot of projects early in the generation, that way maybe you have a lighter 1st or 2nd year, but when the competition starts to heat up from the your rivals (whether Nintendo likes it or not Sony and Microsoft are their rivals as they're console makes, operating in the console market) you have a large stream of games to deliver in later years.

no it means over saturation of the same character and no variety.

Same characters, but gameplay, story, even artstyle can all be different. 

Like Naughty dogs new IPs?

I want more spinoffs. Captain Toad is a must for me. Other spinoffs that were enjoyable were Diddy Kong racing, and Luigi's Mansion.
I want a Sim City style game where you use Toads to build your own Mushroom Kingdom from scratch. You'll have different classes of Toads. A game like this would be perfect for the gamepad. There will be builder Toads, Farmer Toads, and Guard Toads who protect the kingdom. Your goal is to build a kingdom from scratch while fending off attacks from goombas, koopas, and the like. Online coop would be a possibility with various modes from racing to build kingdoms, to defending the kingdom from a horde of enemies.
