BlazBlue Cross Tag Battle was announced from ArcSys Works during Evo 2017. This is a crossover fighting game from the BlazBlue Central Fiction, Persona 4 Arena, Under Night In-Birth, and RWBY Universes.
A tag-team battle format which appears to be featuring 2v2 gameplay. Anime fighting fans rejoice! Not much on a solid release date besides 2018. I would think it would be fall 2018 since they are working on Dragon Ball Fighter Z. Which is scheduled to come out early 2018.
