The release date was listed as August 28th on the game's PlayStation page. It has since been taken down and replaced with the vague "2025" but it still appears at the end of a trailer that leaked alongside the date. You can watch it by inspecting this mossy URL that looks a bit too human-shaped.

Almost 21 years after it first landed, the remake of Metal Gear Solid: Snake Eater will whisk players back to a swampy Soviet wilderness on August 28. The game’s release date was first spotted in a leaked trailer on the PlayStation Store’s backend by the user of a popular gaming forum called ResetEra – and later corroborated by others.

The trailer ends with a really quite upsetting depiction an Ape Escape monkey slapping its butt. From this we can assume, as Eurogamer did for me, that this indicates the return of the Snake vs Monkey minigame, for completion’s sake.
