No MSRP because it's not a product. It's a demo.
And as for whether OLED will be the star of the show, I just have to laugh. It's been heavily featured by Samsung and LG at CES 2012 and CES 2013. And the total global shipments of OLED TVs in the past 2 years are well below 10,000 units. For 2014, no one is expecting the total to exceed 300,000 (and many consider that optimistic), while 4K LCD will absolutely ship many, many, many more than that.
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.
