At this point a lot of the damage is done because even you come up with "killer game idea" it's going to take 18-24 months for said idea to become a playable reality, so Iwata and company really dropped the ball in their planning of the Wii U back in 2011 or so.

That said, what can they do at this point?

- Aggressively try to cut costs as much as possible. Push the tablet idea through till Mario Kart 8's release. If the console is still missing sales targets, then I think you gotta consider cutting your loses and making a SKU available for as cheap as possible ($199.99?) without the game pad. Sorry but you can't piss away an entire console generation because you were married to an idea that just didn't cause any excitement with general consumers.

- I would double down on celebrity endorsements and stop marketing so heavily to kids. It's a turn off to adults. Hire Megan Fox or some other B-tier, but good looking celeb to be the face of a new marketing campaign.

- Go grab Reggie and NOA, tell them to go scour for the 10 most interesting looking indie projects they can find. Finance those 10 projects. Maybe you can find the next Minecraft or Angry Birds, worst case scenario is your console just got a bunch of interesting/fresh new games to play in between all the Mario releases. And funding indie games doesn't cost a ton of money.

- Redesign the system for 2014. Shrink the GPU to 28nm and give the console and game pad a sleeker new look. Use a higher quality screen display too. Expand the remote control functionality of the tablet.

- Swing for the fences with a third party collab. I'm talking Nintendo x Final Fantasy or Zelda x Dragon Quest or Pokemon x Metal Gear Solid (ok, err, maybe not that one). Whatever. And get into development as soon as humanly possible.

- Go grab a movie license. The James Bond game rights are available. Marvel/Disney would probably be open to letting Nintendo make Avengers/Marvel Universe games like the Star Wars deal in 1990s. Nintendo may simply not have the time to create a big new IP this console cycle anymore, Bond sells well on Nintendo platforms and a high quality Marvel game would sell well on both Wii U and 3DS platforms. Both bring in slightly new/different audiences too.

Porting and emulating are two very different things.

First, I'm a Nintendo fan too, certainly more of one than anything MS put out, I think it is best for them.  Nintendo are creatively dead compared to their old NES/SNES/N64 days and they need a kick up the arse from from stiff competition they're only going to find on other consoles.

Second, running something on emulation is a lot different than running a port.  I figured make the CPP required for N64 games to help with lack of buttons.  If a worthwhile emulator let people map their own control schemes.

Well, I hope that Nintendo is in charge of the controllers. Going from Gamepad to Dualshock would be a downgrade.

As for me? Here is my strategy to rape Sony and MS:

- Buy Valve (to handle the online part)

- Buy Crytek (to create engines)

- Buy nVidia (to create hardware)

I've seen all of the comments you make. At best, you are a former Nintendo fan.  Just like what many Sony fans now say.

Second part, I already answered both to someone else and within the post I made myself.  Yes, they are very different.  But I wasn't claiming that the DS could run an emulation of N64 games, I only mentioned the port for effect.  To highlight the 3DS' capability by showcasing another systems.

and yes, I was thinking the same thing with the CPP and button mapping.  However, if I were in charge of Nintendo and this whole process, I would try to find a way around it (in addition to the CPP idea).

I would release the WiiU for 300 (put your currency here, we don't do exchange rates in Nintendo) between October-November, bundled with WiiU Play containing five tablet/wiimotes asymmetric Mii-ni-games (a few taken from the demos).

The system would also launch with the eShop having access to all previous Wii online software (transfer option available); plus a few WiiU software like those screensaver (garden, street) and that drawing game.  I like the idea from freebs2 of having the first few lesons of Art Academy available for free as the first WiiU demo. Also launch would also have media streaming software for Netflix, etc, and Nintendo's own title called Wii TV compatible to stream via the 3DS through UPnP and to/from other UPnP devices/servers.

Second U controller bundled with a game made specifically for two U controller asymmetric gameplay, sold for 90.

Nintendo launch software: Art Academy Wii U, New Super Mario Bros. Mii.
Third party software: Killer Freaks, Pictionary and some improved HD ports.
Retail games prices similar to the Wii, sold between 50 to 60.

The launch window would have: Big Brain University, Pikmin 3, Wii Sports U, new Retro game. During 2013, the first month release would be Wii Fit U + sensor band, with a later release of Endless Ocean 3 and a gyroscopic detective game during spring, leading to Mario Kart and Metroid for the fall.

I like your idea of the WiiFit integrated in the OS. I'd have it work with the 3DS and those DS pedometers, they would connect through the IR port on the U controller. I'd also implement some comunications integrated to the system (independent of the game), and through a profile page a social hub is shown via the U controller which lets you see your friends, chat with them, talk to them or even video conference while playing games.
