According to a page on Sony’s official North American website, firmware 2.53 for the PlayStation 3 is due out by tomorrow. The update, as evidenced by the version number, is a minor one that adds full screen playback for Adobe Flash 9 content.

New for 2.53: The Internet browser now supports full-screen mode for Adobe® Flash® Player content.*

This feature should come in handy, especially since YouTube recently added support for 720p videos.
