The last Professor Layton game came out a fair number of year back. There was technically Layton's Mystery Journey: Katrielle and the Millionaires' Conspiracy in 2017, but that focused on Professor Layton's daughter. The last actual "Professor Layton" game came out for the Nintendo 3DS in 2013/2014.
Well, it looks like Level-5 is bringing the good Professor back as they announced Professor Layton and The New World of Steam for the Nintendo Switch.
Not much about this new Professor Layton title was revealed. We don't yet know the release date nor the price. All we know for sure that it's coming out for the Nintendo Switch eventually.
