Ever since its reveal during July's Evo 2017 Championship Series fighting game tournament, not much was known about BlazBlue Cross Tag Battle aside from the fact that it was clearly set on being the wildest fighting game incarnation ever. We've waited a few months now for more details on the tag-team style 2v2 fighter, including specifics on who we could expect to appear in the game. From viewing the trailer, we saw Jin Kisaragi included from the BlazBlue side of the cast, so of course it's fair to expect appearances by other characters from the other three properties, Persona 4, Under Night In-Birth and mind-blowing still, RWBY.
Jin is confirmed.
Aside from the obvious, the inclusion of both Linne from Under Night In-Birth and Yosuke Hanamura from Persona 4 are welcome additions. Curiously, no additional characters from RWBY were revealed just yet, which makes me wonder if Arc System Works simply doesn't have footage of anyone aside from Ruby Rose in a presentable state yet. I don't think that idea is too far-fetched, considering all of the other characters and sprites are seemingly grabbed (or at least modified ) from previous games.
Still, I hope we can look forward to more of these little updates as development progresses and the 2018 release date nears. Heck, the trailer itself even ends with a cryptic "You can't be...?" from Ragna, so we know some big reveal has to be in the works!
