Deluxe might outselll Wii U's version, but its ceiling wont be much higher.
After that Im guessing there wont be a MK9, instead Ninty will pull a M$ and go straight to Mar10 Kart. IMO they will avoid the number "9" title to symbolize a refresh or rebirth of sorts. a simple Mario Kart Switch would suffice.
