I just realized that more time has passed since Smash Ultimate’s last DLC than had passed at that time since the game’s release
I really don’t know how the future of Smash will go. I highly doubt Sakurai’s current game is Smash based on what he’s indicated in his YouTube series, so if he were in charge, the next game would be at least another three years out from now, and that’s being generous. They could get someone other than Sakurai, maybe as further justification to reboot the series since making something even bigger than Ultimate while keeping the important stuff from that game would be difficult (especially if master-negotiator Sakurai isn’t involved). Or they could take the lazy way out and get Bandai Namco to throw together a Smash Ultimate Ultimate, maybe supervised by Sakurai, but that would involve making a slightly-improved remaster of a game that a lot of people already have, on a system that can already play said game.
