First off, welcome to the forum steamroll9!
As you might be aware, the newest HDMI v.14 brought us some new fetures, such as 3D / ARC / ETHERNET, so in order to take advantage out of these features, you must have the v1.4 chipset on all sources, such as your TV, AVR, BDP and so on.
As for the HDMI cables, you'll be just fine to x-mit 3D signals thru any good High Speed cable, also known as Cat. II (with a 10,2 Gbps bandwidth), EXCEPT for ARC and ETHERNET functions,though.
I've heard quite recently, though not sure about it, that with some High Speed cables ( former 1.3b version ), you DO have the ARC function activated, whereas in some you don't. This is due to the internals having different pinout connections though. I've also heard that the newest HDMI cables in compliance with ARC / ETHERNET functions, have an extra pair of twisted wires in the internals. Not sure either...
In case you do need these 2 new features later down the line, you better grab a spefic HDMI cable that complies with such and you'll be golden!
BTW, would like to hear more people chiming in 'bout this!
