On October 3, 2017, it was announced that the next Arc System Works Twitch live stream to feature new information on the cross-over fighting game BlazBlue Cross Tag Battle would take place on October 20th at 8:00 PM JST (4:00 AM PDT / 7:00 AM EDT).
During the September live stream, Persona 4 Arena‘s Yosuke Hanamura was announced as a playable character in the game. Today, the official Persona series Twitter account retweeted the October 3 tweet, teasing that only two characters from Persona have been announced thus far, but that there will surely be more.
A second character introduction trailer was shown during RTX London 2017 earlier this month, announcing Rachel Alucard (BlazBlue), Hazama (BlazBlue), and Weiss Schnee (RWBY) as new playable characters.
BlazBlue Cross Tag Battle will be released for the PS4, Switch, and on Steam in 2018.
