Koller also mentions a new Metal Gear Solid for PSP is in the works, which may be the subject of the current Kojima Productions countdown nonsense (seriously, stop). Also, around the 15 second mark of the leaked Qore video, footage appears that bares a striking resemblance to Warhawk -- but (as comments have pointed out) the ship appears apart of the Jak & Daxter footage reel. Other clips include footage of LittleBigPlanet and Jak & Daxter.
Let's hope, for Sony's sake, this video doesn't encapsulate the lion's share of announcements the company was planning for June 2. Incidentally, crack out those bingo cards and a big red marker ... you have a few things to cross off.
