Producer Noriaki Okamura says Metal Gear Solid might get more remakes and fresh games down the line, but nothing is locked in yet. He pointed out that each game in the series would need its own remake strategy since the franchise spans everything from old pixel art titles to modern cinematic stuff. The approach they used for Delta Snake Eater would not work across the board, which hints that the original 8-bit games probably would not get the full 3D treatment.
The one game everyone actually needs on modern systems is Guns of the Patriots, since it is still trapped on PlayStation 3. Okamura mentioned the PS3 development was notoriously awful, and the game has some weird, complex code that would make updating it a pain. Most other entries are already playable through backward compatibility or remasters, so there is less urgency there. Fans are hoping for a Master Collection Vol 2 that finally brings the fourth game forward.
