PS3 update 2.53 is out today.
Sony's PlayStation 3 is getting a firmware upgrade today bringing it up to version 2.53. The biggest updates are support for Flash Player 9 as well as full-screen Flash support.
Unfortunately, the Flash updates are the most noticeable as this is a minor upgrade. But fire up those PS3s anyway and load up the newest system upgrade to get the improved Flash support. It may help you enjoy those new higher quality widescreen YouTube clips.
