So I'm not capable of understanding high-level tech talk, but it seems like sony is not ruling-out use of the PS3 with HDMI 1.3 tvs. Is the second video saying that basically the 3d video will be sent out via HDMI 1.3 at a 1.4 bandwidth, but the audio and other features will not? If so, we could get 1080p to both eyes.
This leaves hope for DLP checkerboard owners who have HDMI 1.3 tvs. In my case, I don't have an audio receiver with HDMI pass-thru anyway, so all audio is passed via toslink. And I don't recall sony anywhere actually saying the upgrade wouldn't include checkerboard support. It certainly seems they would have some economic incentive to make it apply to more than one format (there is at least one potential PS3 buyer waiting to see if his TV would be supported). And I would guess for the next year or so, there will be more checkerboard owners than other format.
