Release: Scheduled for 2023... maybe.
Platforms: PS4, PS5, Steam, Xbox Series S, and X.
The game will have a Single player story mode called World Tour. Will also have Classical controls, and Modern controls. As well as have a Multiplayer mode called Battle Hub, what it entails is up for debate as there is speculation that it will be cross platform, as well as a type of PlayStation home type of area. Then again that could just be a overly impressive concept art. The game will also have in game commentary, and just by listening to samples it appears it would be a feature enjoyed when turned off lol
Also the entire roster has apparently been leaked:
