I still think a sequel may come but not right away. It would probably at the Q4 of 2021 or the beginning of 2022... preferably the former.
Not much I can say for gameplay other than add things and make mechanical tweaks. Single player content and online netcoding could definitely use work.
Story Mode is a dull thrug that needs to be redone from the ground up and Arcade Mode is an unbalanced mess (not to mention it could use character-specific mini-stories). The netcoding for online doesn't fair much better as input lag and sudden connection loss still plague matches.
Also, ArcSystem Works is under contract with Namco Bandai and they definitely would want that extra ¥.
