VGC revealed in a recent podcast that KONAMI appears to be planning to announce the long-rumored Metal Gear Solid 3: Snake Eater remake, a new Castlevania game, and the in-development Silent Hill game during E3 2023.
Given that KONAMI has already revived the Silent Hill series, it might only be a matter of time before they announce the revival of MGS and Castlevania series. However, it is believed that these series will also be entrusted to third-party developers for production, although it remains to be confirmed by official sources. Additionally, even if these projects do exist, we may need to wait until after the release of the Silent Hill remake for more news.
