Sony has yet to announce anything on either front. As concerns the OLED, the collaboration possibilities are certainly interesting/probable. As concerns the CLED stuff, we really will hear something about commercialization well ahead of it happening. Feel free to speculate, of course (it's AVS), but absent some kind of announcement, they still have no way to build it and there are legitimate questions about the economics. I'd love to see it, of course, as evidenced by my many posts on it after CES. But let's wait until we hear them commit some yen to the project.
There is no difference in HDMI cables. If you can see the picture without visible dropouts or sparklies, the cable is working at 100%. No other cable will display a better version of that picture. You're simply wrong if you think there is a better digital cable than one that is already working.
