It looks like the arrival of firmware 2.53 is imminent, according to the official PlayStation website. The site, which is clearly written by someone a few days in the future, states that "an update to the PS3™ system software was released on November 26, 2008. You can use this update to upgrade your system software to version 2.53." Nice to know, but what does it do? The website doesn't give much of a clue, except that "the Internet browser now supports full-screen mode for Adobe Flash Player content."
A nice feature, but we're hoping there's a little more substance to make the update worthwhile. No doubt we'll hear official word from the PlayStation Blog about it before it hits.
