Metal Gear Solid Master Collection volume 2 will include MGS4, Peace Walker, and MGS5. No bonus games this time. After volume 1's mixed reception they're taking great care to port MGS4 properly and aim to have a build that hits a solid 60fps at all times, with a 4K option for current gen consoles and PC. Players who already own MGS5 can purchase the definitive edition as a less expensive "upgrade". It includes mission 51, which Kojima was privately consulted for but this will not be publicized. No other changes to the rest of the game aside from graphical enhancements.

Depending on how well volume 2 does Konami is considering a "bonus" volume with all the non-canon side games: Ghost Babel, Portable Ops, Acid, Revengeance, and Survive. Unfortunately no Twin Snakes because Nintendo refuses to let go of it, most you'll see there is a Gamecube NSO release.
