Maybe they should have just ditched the Wii name, or kept the Wii brand centered around the existing console for beginner gamers.
I'd call the new system The New Nintendo Entertainment System (New NES) or New Family Computer (New Famicom) in Japan.
I'd bump the specs so they're a reasonable generational leap beyond the 360/PS3.
I'd probably keep the tablet controller but push the living room functionality of it, it's not a bad idea, but Nintendo needed to make it work with more devices (PVRs and what not) better. Maybe they should've partnered with Google.
I'd have changed the priorities of the New Super Mario Bros. project too -- raise the production value and make sure the game satisfies the hunger of Nintendo fans to have a "big" Mario or Zelda game around launch. They were too lazy with the game, considering they had 3 years to work on it. Cheap midi music and recycling environments and art assets from past games for your "flag ship" launch title just sends the message that you're not willing to put in the effort with your new console, so why should consumers?
