Only announced for Japan, at the moment
Not all platform releases are born equal. PlayStation 3 owners got the short end of the stick with the release of Zone of the Enders HD Collection. While the game played favorably on Xbox 360, the game’s frame rate took a serious hit during boss fights on PS3. It only took six months, but Kojima Productions finally announced a patch is incoming.
Only Japan has been addressed, at this point. The patch will also be included on future retail version of the game. This news comes from Kojima Productions’ online radio show, translated by NeoGAF user raven777.
