Platinum fans are an interesting lot, seeing as they pride themselves with understanding the machinations of the studio's work and are vocal about its technical elements and the challenge they provide, but the flip side is that Platinum games almost never sell well unless backed by a recognizable brand, which means their fanbase is a vocal minority. This is potentially advantageous, seeing as Nintendo has become more open to sharing their IPs, but with how Car Fax Zero turned out, I am wary of future partnerships with Platinum, and I think many of the creative forces at Platinum would agree. Kamiya seems like someone who likes making his own, original IP, and while I respect the thought and experience the guy has, he's yet to make a game that has truly won me over.
I just wanted to add a disclaimer: I think Platinum games are marvelous when in the hands of someone who has learned their intricacies and I get a huge kick out of watching high level play in the same way that I enjoy fighting games, but they aren't for me.
