September 9th, 2021
So September 2024 is the best guess if there will be one in 2024. This could be like 2022 where there will be no Showcase but I said this many times before.
Since 2016 Capcom loves to reveal a new Resident Evil Game at a PlayStation showing. I believe only Resident Evil: Resistance, RE:Verse, and Resident Evil 4 on Oculus Quest 2 VR, were the only Resident Evil reveals not done with PlayStation for the past 8 years. Unless you count the Mac/iOS, and Switch cloud ports of the RE Engine games as new game reveals.
We are long overdue for a new Resident Evil game announcement and I think revealing RE9 at a PlayStation showing in September is what is most likely gonna be what happens.
RE7 was revealed at PS E3 2016
RE2 Remake was actually revealed at PS E3 2018 (It was announced on August 12th, 2015 on Capcom's Facebook page.)
RE3 Remake was revealed at the December 10th, 2019 State of Play
RE8 Village was revealed at the PS5 Future of Gaming showcase
RE4 Remake was revealed at the June 2nd, 2022 State of Play
and 2024 has yet to reveal a new Resident Evil Game
edit, check out this cool breakdown of all the Showcases I found on Reddit!
