Just saw Platinum there after others mentioned it. Ugh, no. It's a company with a long history of failures and some terrible creative direction. They're a much better developer when they're working under supervision on someone else's project. Leave them in their current niche. Well, unless they could get rid of Kamiya first somehow.
I don't see them considering more than a couple of Japanese studios, anyway. The west is their focus and it's where the most potential exists.
