According to PS3 Center, the latest issue of PSM3 reports the following rumour:
“MGS maestro Hideo Kojima’s got some big announcements for E3 in June: one a quasi-logical step for an existing game, the other… well, we’d be shocked if MGS5 wasn’t on the table at some stage. Or under it. In a box.”
The company has taken on staff for “next generation” Metal Gear projects.
