E3: Kojima Announcing 2 Games, MGS5?

The Electronic Entertainment Expo (E3) seems to come around sooner and sooner each year, and we're already starting to hear rumors about what might be announced. The latest rumor from PSM3 magazine in the UK is that Hideo Kojima will be announcing not one but two games. They write:

"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."

So we may see Metal Gear Solid 5 finally announced 3 years after the last game released, but what's the other title that's mentioned? Zone of the Enders? Peace Walker for consoles? We'll have to wait and see.
