Won't work as replacing one console with another undermines consumer's trust.
The problem of the Wii U was/is that it isn't that clear how games are going to be played. With the Gamepad? WiiMote/Nunchuck? Both?
Don't forget that the original Wii Sports was THE system seller. And Nintendo didn't release a follow up until Wii Sports Club. That wasn't that smart. Also shutting down the Wii Channel before having a chance to show Wii users the Wii Sports Club on the channel...
Nintendo needs to release some great software for the Wii U. That will help selling the console.
