Looking back through the lens of hindisght, the lack of the 60s and 65s should give one more than pause. They really didn't ship but a few thousand 65s in all of 2010. Will 2011 be different? Sure, but how different. Further certainty that the 75 is likely to be mythic this year.
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.
