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.

Sony may have spoiled the release date for Metal Gear Solid Delta, though the story beats will be very familiar to anyone who played the original.

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.
