Kojima and Frank Miller co-project finally revealed. A PSP slideshow comic, announced on his blog.
12:09 Scouring the interweb this morning, we happened to turn up quite a tasty little morsel of newsworthy info. Mainly that something called Metal Gear Solid BD is in development for PSP. How do we know? Well it's noted on Hideo Kojima's blog itself. Interestingly it was reported in Famtisu recently, that Frank Miller of Sin City and 300 fame and Kojima met to talk life and business and according to some, MGS: BD was the main project they met to speak about.
When we might expect MGS:BD is unknown, but what is interesting is that in pre-MGS:Ac!d interviews, Kojima discounted a 'proper' MGS game for PSP due to the limited control system (a polite way of saying the analogue stick is dreadful). Our best guess is a slideshow comic Sin City-style, and since we loved the noirish movie, the idea certainly has potential.
As for how MGS: BD slots into the overall MGS story, we simply know nothing at present. We approached Konami for comment but they appeared to be equally in the dark at time of going to press. More when we have it.
