Good news: Hideo Kojima is making a new game. Bad news: information is a ways off.
Kojima took the stage to confirm what we sorta already knew regarding the Metal Gear Solid HD Collection on the PlayStation Vita.
Then he announced that he's currently working on a new original project, one that will release for both the PlayStation 3 and Vita, and will take advantage of that nifty "transfarring" feature (which got a logo of its own at the conference, by the way). We have no idea what that project could be, but as he called it "original," it probably isn't Metal Gear Solid 5 . So maybe it's an all-new IP and that's enough to get us excited; we've always wanted Kojima to branch out and try new things. He's too talented and too much of a visionary to stick with only one or two franchises (as amazing as those franchises have been).
But as I just said, the downside is that when asked when we could expect new details on this mystery game, Kojima could only answer- "It will take a while." 'commences waiting not so patiently'
