As the title says.

With the Wii U I think being it was their 1st HD console there was a bit of a learning curve N64 to GCN like so it was easier going from GCN to Wii.So I think they wont have game droughts going forward.Not to have the previous consoles name in the new one.

Well, I am hoping they learnt that not to make a stupid name, not to fuck up the launch, properly market your product and that third party is important so to make their next console in such a way that makes games easy to port

Don't make your marketing team a bunch of apes

I don't know what they actually did learn, but there are a few things that I hope they'll try to amend with their next console.

1. More third party support

2. More hardware space

3. Launch your system with the games everyone wants rather than selling them 2 years later

4. Try to make more powerful hardware

5. Better advertising is necessary

6. Pick a better name for their console

never call your next gen system like an adon from your current system
never put gimmick controls in who make your console more expensive
dont assume casuals are loyal to your brand

i hope at least

That the casual market is huge but incredibly fickle, and you deride core gamers at your own peril.

Don't base the power of your console on last Gen:
Wii U- Ps3/Xbox360
Wii - Ps2/Gamecube/Xbox

For the love of God just don't give the next console a stupid name. That goes for you too Microsoft.

-They learned that a a brand name can't, on its own, guarantee success: the 3DS (successor of the DS) problems the first year and the WiiU (successor of the almighty Wii) lackluster sales are a proof of that.

-They learned that 3rd parties are unstable, but necessary to avoid software droughts. A lot of companies promised to support the WiiU, but they backed out at the last moment. Nintendo needs to choose wisely which companies to help and listen to in hardware and software specs and which ones to be weary of (I'm looking at you EA, you boicotting thing).

-They learned to avoid focusing too much on one console while ignoring the other. 2013 was lacking for the WiiU and fantastic for the 3DS.

-They need to grab new audiences, but concentrating on their core and on regular gamers. Look at the Wii Sport and Wii Fit sales and compare them to their WiiU counterparts, and then do the same with Mario, Smash and Zelda games. Which ones have resisted more with a smaller userbase?

-They need to pay attention to their deals with other companies. I'm sure that making Sonic Boom exclusive has been a soooooo much beneficial to the WiiU.

That what worked once might not work twice
