I've always wanted Nintendo to unify Excitebike, Cruisn', Excite Truck, Wave Race, Pilotwings, and 1080 Snowboarding into one racing-sports franchise and just call it "Excite".
It'd be sort of like Wii Sports Resort, but more realistic and deeper racing gameplay and customization options - but still kind of arcadey.
I predict NX launches in 2017 - not 2016
