Atlus revealed that Persona 3 Dancing Moon Night and Persona 5 Dancing Star Night are headed to the PS4 and the Vita in Japan next autumn.
The release date for both is "Spring 2018" (so Autumn in Australia) and there's no word if and when they will be released outside Japan. Have a look at their debut trailers below:
Since the official site lists pricing for each, it seems they will be sold separately, but don't be surprised if there's the inevitable bundle.
Persona 4 Dancing All Night was released in Australia in November 2015. In case you missed it, check out the Kotaku review right here.
