Firmware 2.53 coming November 26
According to the Official PlayStation website, PlayStation 3 owners can expect their next firmware update on November 26. While whoever wrote the information may be a little ahead of themselves or in a turkey daze for this Thursday, it doesn't look like the notification was meant to go up.
"An update to the PS3™ system software was released on November 26, 2008."
The only details given for the update involve full screen flash support for the built-in web browser. Though it is a nice feature, hopefully there is a bit more to it than that.
