I would of sabotaged sony's and ms's consoles a year or two into their respective development. Push them back a year or two. I would release the wii2 with a normal controller that's similar to the others. No gamepad. It would be priced $50 to $100 cheaper but made the console a bit more powerful. I would become fast friends with third party developers.

I would competitively price the wii2 games and let youtubers make money off of nintendo game vids. Add being able to watch dvds and blurays on it. I would deliver all the nintendo games the fans would want but also push a lot more mature games out to raise interest in the core gamer demographic. More casual games wouldn't hurt either. I would try to time releases so there's less dry spells. Release ZeldaWii a few months before the ps4 and xbone came out.

That Wii GameCube controller is amazing huh? That's why Nintendo won't do it lol.

Pretty much kept everything the same except make the Pro controller the standard and move the sticks on it lower and have analogue triggers. Also priced $50 cheaper at launch. Oh and had a trophy system in place at launch.  Not to mention had movie playback at launch.  Forgot to say I would also have changed the name to Nintendo Revolution which is the most badass console name ever used or not used.  OR Nintendo Kitana the codename for the Dreamcast.  Seriously why are the code names sometimes more badass than any console name ever yet they remain unused?  Other than dolphin that's just stupid.

I'd keep the power PC CPU for the sake of backwards compatability. Third party friendlyness isn't worth losing that. They never get the third parries anyway. But id consider clocking the cpu a little higher if the cost was ok. I don't think powers the biggest issue for the Wii u. A better name and better battery life are key improvments. Maybe give the gamepad a slicker styling and a non gloss finish.

Anologue triggers are a debatable issue. I personally perfer digital for any game that doesn't make especially good use of Anologue... pretty much all of them. Id like the top shoulder buttons on the gamepad to be more egonomic though.

Finally... (and this ones risky) with hignsight I don't think they were ready at launch and they squandered their year advantage - dirtying the systems name In the process. I would have delayed a year, so it came out with the compertition, and given it an awesome day one launch line up and a funtional os. 32 gig model only and every system packaged with Mario 3d world preinstalled. Day one the Wii u would have plenty of great games and the other consoles would take a year to begin to catch up. Would have also payed big money for Rayman legend and sonic racer transformed exlusivity. And not bothered publishing ports of old last gen games.

The GameCube's D-Pad and four button layout are terrible for Virtual Console and some multiplats

I would have ditched the gamepad and instead made new and improved Wiimotes and nunchucks. Instead of a giant A button, it would be 4 small buttons. ABXY and feature the diamond layout. The B trigger would have 2 buttons instead of 1, or that 1 trigger would be analog. I'd improve the speaker, and include a microphone, and I'd make a improved nunchuck with a better motion tracking and instead of a giant Z and a small C button I'd make 4 buttons or make the Z button a analog trigger. Use the same quality battery as the Pro Controller, and you'd be all set. You'd have most of the buttons of a pro controller, but the option of tighter motion controls with the improved nunchuck.

The extra money saved from scrapping the gamepad would go towards improving the specs of the hardware. Instead of 1 GB of RAM I'd go with 4 GB of RAM and beefing up the CPU and GPU. 2 GB of Vram and a 250 GB HDD. I'd also not shape it like the Wii and name it the Wii 2. I don't even care if its shaped like a pyramid with a flip top, it won't be shaped like the Wii.

They couldn't have created another Wii phenomena, but they could have done far better than the Wii U. Really their next move was simple:

-Release in 2011 instead of 2012
-Release with something at least 3-4 times stronger than the Wii U (HD 6670, quad-core AMD cpu, 4GB of RAM, HDD)
-No Tablet
-Call it "Nintendo HD"
-Have a unified online system that is at least as good as the PSN back in 2006

Back in 2011 the Wii still had some good will going, and a name like Nintendo HD would have sent a clear message as to what the system is. The components I proposed are not that expensive and with no tablet jacking up the price they could have easily sold this thing for $300-$400. Then in 2013 the NHD would have been out for 2 years as the ONLY HD console, and it would probably be $200-$300 to compete with the PS4/X1 release.

No it wouldn't have sold gangbusters, but it would have done well 30-40+ million.

Definitely not doing that with a low end AMD CPU ...

I'd not change much hardware wise, but Mario Maker and Kirby's Rainbow Curse would have been launch titles, with advertisements that really push Kirby as a fun co-op game. Also I'd have launched last and with more games,

I don't think the CPU was ever the problem, well at least not the way people thought it was ...

The only issue with the Espresso is the low throughput due to IBM making little to no updates on it's micro architecture so anything else modern would've been fine in this aspect ...

Since the GPU was it's biggest issue I would've went with somewhat beefy GCN GPU ...
