Atlus in Japan has registered a bunch of sites recently. with the names p5d.jp, p5r.jp and p5u.jp and p5ag.jp listed. Its not too far of a stretch to imagine a Persona 5 Dancing game, and a Persona 5 Ultimax fighting game using the characters from the new episode. What the others are could be anyone's guess, but the chances of a Persona 5 Golden seem to be slipping fast as Vita sales in Japan.
2015's Persona 4 DAN was fun, but jammed with too much chat, and fluff. Hopefully any future game, assuming it came to Vita would be tightened up. However, Switch or other formats are now more likely.
