This is probably a 50/50 but I have to say Clover Studio. Ok granted Okamiden is coming out soon but what if they were more successful and a sequel to okami was release on the PS2 or PS3? The reason I saying 50/50 since we got good games so far after their demise and reform to Platinum Games (Bayonetta, Vanqish and Infinite Space, well Madworld wasn't good).
