Hatsune Miku will be back in 2016 to give the Vita another dose of vocaloid tonsil teasing and rhythm action. A 'new' game is due in March for the Vita, and later in the year for PS4. I say 'new' as I suspect there could be a fair amount of remixed, remastered, or just borrowed material. But it looks like there's some new artistes on board.
The trailer celebrates the games across the series' eight-year history, with most of the big hits on PSP and Vita. the "Xth new project", will probably pick up a revised name, anyone guessing on Hatsune Miku G?
Not sure if anyone will wait for Sega's dopey western arm to port it, so imports seem to be the order of the day, along with mass setting up of Japanese accounts to get the presumably endless DLC.
