Sony is set to release an update to the PS3™ system software with the 4.31 official firmware. Whether it is a direct response to the release of the Rogero 4.30 cfw is still a hunch. Because the 4.31 update has been looming since games like the Monster Hunter HD has been reporting problems with the 4.30 firmware update released last October 24, 2012. However, good news for 4.30 cfw users is that the update is not mandatory and you will still be able to access PSN with 4.30 cfw. Meaning, you wont need to wait for Rogero to release an updated 4.31 cfw to access PSN.
This firmware update won’t “affect online play and access to apps” and does not signal PSN maintenance. Additionally, it’s not a mandatory update, though it’s designed to “improve overall system stability” and is thus recommended by Sony.
