http://www.siliconera.com/2015/09/16/new-sword-art-online-game-development-announced/ Considering the first three are Infinite Movement (PSP), Hollow Fragment (Vita), Lost Song (PS3 & Vita), initially in Japan. Good chance of this one being on Vita as well I imagine. The game will have an official unveiling at Dengeki Bunko Fall Festival 2015, which takes place October 4th. I've played through a little bit of Re:Hollow Fragment on PS4 and still looking forward to Lost Song in November!
