This was the case for three years, but at the start of 2019 everything changed. Instead of a season pass Capcom released a balance patch and one stand-alone character. Websites reported this as the start of season 4, but nothing more was forthcoming. Since then, SF5 has been pretty sparsely updated; over the last five months theres been one new stage and a fistful of character costumes, but compared to previous years the update schedule has been pretty much halted entirely.
Worse still, Capcom has said next to nothing, leaving fans speculating about what changed behind-the-scenes. The most prominent speculation, of course, is that Street Fighter 5 is dead. It isnt as successful as its predecessor (which lasted seven years through updates and re-releases) and has had a generally troubled time right from launch. Maybe Capcom is calling it quits? Well, apparently not, gamers now know.
