The pricing will be key, as will the questions about whether a special screen is needed. Given the ridiculously disappointing developments in large flat panels (way too much money for too little performance), I'm pretty intrigued by this.
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.
