Arc System Works have released a plethora of great fighting games as of late and it’s not stopping any time soon. Leak and datamining X account X0XLeak have discovered that the company is planning a new Nintendo Switch 2 game that is codenamed Watari and is scheduled to be released this November. The unannounced game utilises Unreal Engine 5.4 and it is not clear which franchise this one is based on.
Rumour: New Arc System Works game in the works exclusively for Nintendo Switch 2

An exclusive new Nintendo collab fighter would go demonstrably hard.
It’ll likely be a new IP, but could you imagine something ala Hyrule Warriors?
“Demonstrably hard” is hard
Mario X Zelda by Arc system would be golden.
Considering the art style of the Arc System games, I suppose it is a Fire Emblem fighting game or a new Guilty Gear. But your take would be great too.
Absolutely not. Its something new, Strive season 5 just got leaked, so they’re sure as hell not going to make a new one so soon.
Ufff… that would be a WIN for Nintendo… they better add Link as a playable fighter.
Saint Seiya, One Piece, Black Clover all good options. If Tencent is involved adapt Scissor Seven into a game
Shonen Jump big crossover fighter with everyone including Kinnikuman, Shaman King, Cobra, World Trigger, Toriko, everyone!!!!
99.99% another kunio-kun spinoff
