Guessing an updated MK8. Probably have all the DLC, a few new tracks and characters and some gameplay tweaks. It'll probably be a running theme for the first year of it, taking Wii U games and putting out definitive versions here like with Splatoon and probably Smash Bros. etc. Which, as disappointing as that might be for all of us who've played them on Wii U, is a good idea IMO. It's an easy way to beef up the line up and appeal to those who wanted those games but couldn't see enough value in the Wii U with its lacklustre third party support.
