Famiboards

Its no secret Nintendo is working on the next iteration of one of their most top selling series, Mario Kart. What changes or additions would you like to see in this next entry?

I would like to see specials make a return from double dash. The idea of having that unique ace up your sleeve mid race again is a welcome one in my book.
Similar to Mario Kart tour I would also love to see unlockable character alts/skins. It can give players more individuality and options as well as more use for their coins.

So any ideas or hopes?
