I'm a little surprise that the HDGuru/Gary Merson stuff hasn't generated more excitement or at least discussion here. I guess we'll see what happens over the next few months. Not sure how the Japan situation will delay any of the product introductions -- and it's worth noting how ridiculous it sounds juxtaposing loss of life and tremendous property damage with new TVs; obviously my primary concern is for the Japanese people -- but eventually the stuff will reach the market and perhaps people will get to see if that hype is delivered.
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.
