Just Dance 2017 will be released October 2017 for all systems including PC and the Nintendo NX. It is also the first title announced for the Nintendo NX which is huge information for knowing when potential systems will be released.
To Introduce the game they had people dancing around on stage to a song by Queen "Don't Stop Me Now" It was energetic albeit a bit weird to watch. I imagine they were engaging in a lot of what the core gameplay will be like when the game comes out as they were referred to the "Movement Wizards" Just Dance Team 2017. It will be fun to see what other potential titles are announced for the NX.
