No one mentioned much about 3-D that was new, e39, because there is, in fact, nothing new.
The same lack of content (except for a certain complement of Hollywood movies), the same generally unappealing glasses, the same resolution halving on passive (although 4K promises to improve that)...
But every single high-end TV has 3-D and many were shown off with the 3-D feature, including both 2013 OLEDs (Samsung and LG), LG's multi-million-dollar 3-D wall, etc.
Philips not-a-product, not-on-display glasses-free set might be the future -- hell the only chance for 3-D to go mainstream is minus glasses, that much is clear to every rational observer of the scene (i.e. rule out many AVS enthusiasts from the set in question) -- but it's entirely irrelevant, especially in North America, where there is no Philips to speak of.
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.
