Kojima claims this in interview
the announcement of the latest installment of Metal Gear was announced, we have wondered when we would actually be able to sample it ourselves.
In a recent interview that has been leaked, Hideo Kojima is said to have claimed that Metal Gear Solid: Rising Revengeance will be playable at E3 this June in Los Angeles. He didn’t offer any details of when he expected the game to be released.
While a number of retailers are accepting pre-orders for both the Xbox 360 and PlayStation versions of the game, its release date remains a mystery. While some think it is possible that it might make a release yet this year, others believe that estimate is overly optimistic.
We think we should be able to better tell after we see the demo at E3. At that time we expect publisher Konami to announce at least some sort of release estimate for the title.
