It could very well he a return of Super Mario. Nintendo used the Donkey Kong Country brand again. It would make perfect sense for Nintendo to title NewSuperMario: WiiU as Super Mario 4. Nintendo could do a ton with the original brand.
Nintendo knows their is a lot of strength in brand recognition. I wouldn't put it past them to reboot the original brand maybe include the first three on the disc as a special edition. Nintendo will do good with a reboot that or they could choose to continue the New Super Mario Bros brand on WiiU!
