It's Nintendo and they're a Western studio, so that probably isn't in the cards. Retro Studios needed like 15 years to get an original IP after being restructured and completely bought out by Nintendo and they apparently blew it as the project is canned. I wouldn't expect them to get that chance again any time soon either.
If the Donkey Kong Country IP is still free that might be something they get to work on, but I suspect Nintendo has handed that IP off to another team. The Universal Studios attraction has a Donkey Kong area, so I think they will want a new game for it soon-ish.
