I don't think it would reach MN9 heights, but if IGA did a kickstarter by the end of the week I'd say he'd get a pretty penny. I mean, Yamane is now freelance and both of them are on good terms with Ayami Kojima, so conceivably he can get that 'gang' back together.
I also wonder if some of the other Konami people have also left in the past five years as well, like Curry the Kid, KO-G, and Soshiro Hokkai. The team behind SotN and HoD seemed to have disappeared from the map after 2002. I ask because IGA seems pretty confident he has the actual resources to create a studio, and studios beyond the ZONE and Pixel type tend to have more than one person.
