Update: The PS3 Firmware v1.54 (USA) is now available for download, and listed changes include: [Screen Mode] has been added as an option in the options menu for video chat. The image of the person you are chatting with during video chat can now be changed to match the screen size, and You can now use a compatible USB camera compliant with USB video class (UVC) for video chat.
Although no specific information is available (yet) on it, according to our NEW PS3 Firmware 1.54 Forum thread those who have connected are now being prompted to update to PS3 v1.54 Firmware. It's very likely by later today the official $ony Web site PlayStation.com will also be updated with it as well. More to come soon... and no, we wouldn't recommend updating to v1.54 as it's likely even more secure than previous revisions (meaning you could be waiting that much longer for a PS3 iSO Loader, if the first one to come only supports lower Firmware versions).
Props to boss1337 and Stuntman667 for the initial news, and to everyone who confirmed it as well!
