The PS3 dev kits on display at GDC apparently skipped the HDMI connection for some of their demos, casting doubt on how far along Sony's come with its hardware and digital standards compliance.
During GDC, Sony brought along a few PS3 demo units to show off audio and video, which TG Daily spied from a distance. As you can see above, the PS3 graphics demo unit used a standard AV Multi-Out connector while the "two HDMI ports right below the AV Multi-Out port were unused." TGD apparently offered to lend Sony officials an HDMI cable of their own to connect to the system, but they were turned down.
