So I've been digging around, and last year's PlayStation Premiere was held on July 17 in Japan. At the event, they announced games like Gran Turismo 5 Prologue, Valkyria Chronicles, Disgaea 3, Metal Gear Online, and games like LocoRoco for the PSN. They also showed new FFXIII trailers.
See an entire article on it here.
Who knows, we may see Team ICO's game as well as a bunch of JRPGs announced next week. :D
