Nintendo IMO needs to move to an account based system before the Wii U's time is up. They have one of the richest libraries of games ever made and they need a way for customers to keep and play everything they have bought from Wii onwards. VC needs to be expanded and fully available by the time the next hardware launches.
Also, I think they need to focus on just one piece of hardware. It can have a handheld component, but it should be able to play both console and handheld games. It can stream the more demanding games locally, but should be able to download and play the handheld games anywhere. If a system like that launched with almost every Nintendo game ever made available right from the get go, they would dominate.
