Zone of the Enders is coming back in glorious HD format! Both Zone of the Enders games are being remastered in HD and is hitting the PlayStation 3 AND Xbox 360. Zone of the Enders will be out in 2012.
As for the Metal Gear Solid HD collection, it will include Metal Gear Solid 2, Metal Gear Solid 3: Snake Eater and Metal Gear Solid: Peace Walker. The MGS collection will be out this November. This will also hit the PlayStation 3 and Xbox 360.
Konami states that these HD version isn't an emulator. It's optimized and rebuilt specifically for the PS3 and Xbox 360. There's a new user interface, redrawn high-res 2D art, new trophies and Achievements and improved audio quality.
Additionally, both collections will have a new feature called "Transfarring." Yes, it's really spelled that way. Transfarring will allow PlayStation 3 and PSP owners to share one save that works between the two versions of Peace Walker. So far that will be the only game that works with Transfarring. The feature is also in the Zone of the Enders HD collection but Konami wouldn't detail why exactly. Possible PSP or NGP releases coming?
