What should Retro Studios make next?

I'd love to see them take on something new personally, but I also wouldn't be opposed to either Prime 5 where they can create their own vision from scratch, or a new Donkey Kong Country, as while Bananza is fantastic, it'd be awesome to see the 2D series continue as well, especially as Tropical Freeze was for my money one of the best sidescrollers ever made.
