They should -- spinoffs aside -- probably leave the franchise alone and come back to it ten years from now, when everyone has put it out of their mind but at the mention of it remember all of their beloved memories that have been glossed over with time, and the technology at the time will make it awesome just for the brand new shiny graphics. It won't matter if it's groundbreaking then, everyone will be dying for the sequel to their long-lost childhood or adulthood memory that no one will care what the game is like, as long as it's sorta good.

That's what Nintendo does. Seems to work.
