The current plan for this game "Battle Arena Toshinden Ultimate" is to be released for PlayStation 4 (PS4) / PlayStation 5 (PS5), Xbox (X - Series), PC, Nintendo Switch and Stadia

This are my ideas for a Ultimate Toshinden game, my dream game and i bet this is also the dream game of every Toshinden fan out there :)

I really wish Tamsoft Corporation and Takara Tomy could see this and think about to bring Battle Arena Toshinden franchise back to life nowadays, in case if they won't do anything about it at least should give (sell) the rights of Battle Arena Toshinden to Bandai Namco Entertainment for to make this dream true.

I don't know if this will work but at least i tried, i'm a big fan of Battle Arena Toshinden franchise :)
