That's because PlayStation Showcase is a rare, relatively new branding. Before Sony pulled out E3, these were still "PlayStation Showcases," but they were beholden to the E3 schedule. Afterward, there was the Future of Gaming Event, there were PS5 Showcases, and in 2021 simply a PlayStation Showcase. Sony didn't host a PlayStation Showcase in 2022, with the rumored cancelation purportedly being due to Microsoft's Activision Blizzard acquisition, but many are hoping for one this year. Yet, looking at the two PS5 Showcases in 2020 and the one PlayStation Showcase in 2021, there's not a strong, consistent pattern. For example, two events take place in September, one event takes place in June, and it's hard to pinpoint anything. That doesn't mean fans are completely devoid of information, though.
