I legit would have preferred a proper remake of MGS1 and 2, but I think Konami knows that they can't plan multiple remakes beforehand as it is way too risky, so they chose Snake Eater as the 'quintessential' MGS experience (gameplay, story, characters and settings) and, truth be told, you can play MGS3 without knowing stuff about the rest of the series, you'd miss out on a lot of references but you can still enjoy it as a great Cold War era stealth action game.
According to an IGN article, GameStop "leaked" the MGS3 Delta release date to November 17th 2024, and frankly it stinks.
