The videos are Xbox branded, but Switch did get the announcements a couple of weeks later.
A couple of intended announcements for Sunday were inadvertently dropped early, and one or both may be Switch-bound.
Since-deleted Instragram posts on Atlus's Western page showed an announcement of a "Persona 5 Tactica" with a release date of November 17, and a "Persona 3 Reload" for early 2024. Persona 3 has been rumored to be receiving a remake, and domains for a "P3R" and "P5T" were recently spotted as referring to a 404 page (suggesting impending updates).
The trailer for Reload was also uploaded, with Xbox branding, suggesting the game would be formally announced during Microsoft's summer showcase on Sunday. A similar announcement was made for the modern Persona trilogy - 3 Portable, 4 Golden, and 5 Royal - last year at the Microsoft show, with a Nintendo Partner Showcase two weeks verifying the RPGs would come to the Switch as well.
Atlus messed up. They revealed Persona 3 Remake too early on their instagram pic.twitter.com/xycj3wZZ5d
