Hey thanks, I now feel vindicated. I received a lot of flack when I posted this idea before. If you're right then it all makes sense.
I did a little more research and found that "Lightning Bolt" is a AMD name for their answer to Intel's/Apple's "Thunderbolt", and it is still using the mini-display port and was discussed early in 2012. The USB-3 optical is Intel's "Light Peak" and was demonstrated in 2010. Intel also has a "Optical Thunderbolt", again part of the mini-display port and was discussed in Jan. of 2012.
I don't know which, if any, of these products will actually see product usage any time soon. They all are seeking higher speeds with cheaper cables.
so ... now back to the scheduled thread about Thunderbolt ...
