1 - Change the name, I'd abandon the Wii brand if we couldn't come up with anything better then Wii 2 and go with some like "Who" or "Where/Warez" or something along those lines. Keep it one word, if the brand is changing from Wii to something else.
2 - If specs can be changed, up the memory RAM to no less then 4 GBs is a must. Who thought that 2 GBs would be alright when half of it goes to the OS of the system is being both foolish and far too cheap.
3 - The Gamepad is the standard controller but there will also be a redesigned Wii remote/nunchuk that works exclusive for the Wii U. The original Wii controller still works on some games similar to how the Gamecube worked with some Wii games but the new remote/nunchuk will have a slightly different look even if it the same tech inside of a Wii Remote+. The illusion of change is better then having no change at all.
4 - Build the system from the ground up prepped to handle 2 Gamepads at the same time. Gamepads would be sold by Nintendo separately at $100 (no more then $120) each, the first system a gamepad is activated on is the gamepad's home system so Mii's can only be created on it, although friends can still share. Heck, the gamepad itself will probably need to be souped up so that it stores at least 3 Mii profiles on the device itself and can be used when playing on another Wii U system and allows both players to access the Miiverse separately. One if not more of the launch titles (Mario Bros U especially) will have two Gamepads multiplayer as a prominent but not mandatory feature. Two Gamepads locally means no online multiplayer at that time, although Miiverse would still be available.
5 - The 32 GB hard drive is the basic version sold at $325 to $350, it would have a pack in game (Nintendoland) or at least a demo and both the Gamepad and the new Wii U remote/nunchuk.
6 - Not really a launch move, but if I was Nintendo, I'd also eventually announce (after Sony and Microsoft release info on their systems) that a updated Power Glove would be released with certain games in mind... like Wii Fit U (or whatever it becomes) partially because I figure it will cause the older fandom to jizz at possibily finally being able to realize its potential.
Edit: Just realized the Power Glove was made by Mattel, so if the trademark covers ALL possible viable game related glove controllers, enter into a limited partnership where the device is literally meant for a limited run and not necessary for the games it works on.
