Masahiro Sakurai, the director and creator of Kirby and Smash Bros., confirmed that he’s working on a game according to Source Gaming. There was no other details given. Sakurai also stated that while looking around the development room, there’s not a lot of people who have developed for the Famicom anymore, referencing his age and longevity in the industry.
Could this mean a port of Super Smash Bros. to the Nintendo Switch? Could it be a new Kirby game or is it something else entirely? Is it possible he and his studio are making a game for a different device altogther (his studio is not owned by Nintendo). Only time will tell. Whatever it is, we will be looking forward to it.
