PS3 is receiving a significant firmware upgrade tomorrow. 1.80 allows PS3 users to playback DVD movies and PlayStation 1 and 2 games in full 1080p resolution. Another feature added to the upgrade is Advanced Remote Play: it was supposedly added in a previous update, but many frustrated gamers were unable to get it running.

With Advanced Remote Play, PSP owners can access content stored on the PS3 from any wi-fi connection in the world. Not only will the new PS3 1.80 firmware be necessary for Remote Play to properly function, but according new press materials, PSP firmware 3.50 will also be required. According to Sony, firmware 3.50 will be available "at the end of May," although more specifics were not provided. Additional enhancements to be found on the firmware were not made available, but we're thinking it might have something to do with PSP's newfound VoIP functionality.
