A relaunch would have to include the following things:
- redesign of the console to make it look more friendly and less like the Wii (!) (+ quiet, more and faster storage, ...)
- redesign of the Gamepad to make it smaller and look less intimidating (the reason people bought the DS Lite but not the original DS was because the phat model looked intimidating. Back in 2005 Nintendo knew this!)
- a game included in the basic package
- a price drop
- include a Wiimote (yes, really! Because people don't even know they can use one when they buy the damn thing)
- a new marketing campaign making it clear this is not an add-on for the Wii (everyone I know thinks this! They all ask "why do you have two Wii's?"
They basically need to make the Wii U attractive and inviting to everyone. Also, they have to stop with the mixed messages! Currently the basic model (for the mass market) comes without a game! What the hell? That's not how you target price sensitive market segments! And the premium model (for the "hardcore" gamers) comes with... Nintendoland. Seriously! If you try to sell your premium console to the "hardcore" gamers at least bundle a game with it they actually want. Nintendoland is the game designed to get the mass market, right? So why don't you bundle it with the package for the damn mass market? It's like Nintendo doesn't even know marketing 101.
The gamepad is cool and all but Nintendo sacrificed oh so many things just to get that gamepad out there: price, user friendliness, the heritage of the Wii, their image as a mass market company... and it didn't help them get the core gamers at all. They just should've bundled a Wiimote and a Classic Controller with the console and both core and mass market would've been happy. And something Kinect-like. Nintendo could've made more money off a camera than Sony and Microsoft combined (just imagine the next Wii Fit craze! Or Nintendogs on a home console. Or the many minigame collections Nintendo has that would've profited from a camera system.)
