Light Peak technology

I just found this clip on YouTube and it looks like it could finally give an answer to how flexible or lightweight a BNC cable can be.
While it definitely goes beyond the needs of HD-SDI and could certainly carry the signal from camera out (curious to hear about it's duplex capabilities), I think it has a few factors going against it. Fiber optics and fiber technology, while flexible, doesn't usually appreciate extreme bending, standing on, etc. Anytime someone steps on the cable, they could split the optic line and potentially destroy the cable.
Personally, when it comes to operating with an HD-SDI cable, I have a few of these in my kit, and they haven't let me down yet:
Extremely thin, female on one end. I'm not fond of the crimping job, but they get the job done.

If they can implement the optical version of thunderbolt in the next couple of years, I would be very happy to see a thunderbolt / SDI hybrid connector... I can dream, can't I?

While the thunderbolt may use a displayport there, that particular setup is designed so they could attach displays, but that's not all the thunderbolt can be used for. Intel wanted a next gen all-in-wonder solution to connect everything to one port and the thunderbolt is what they're offering. It's PCI-E and will be compatible with (I think) every I/O on the market to include USB and firewire. It's not just the cable and it eliminates much of the bottlenecks associated with the other ports when connected directly and not through a firewire or USB adaptor. It can send power as well, so conceivably some computers out there will ship with one port for everything, monitor, I/O, etc. I can totally see Apple doing that for their lower end devices as they sort of already do, even with their desktop. Here's hoping they don't remove the already small amount of ports on the Macbook Pros. For someone like me with a heavy post production background, the thunderbolt is freakin' great. Presently it's nearly impossible to edit much more than DVCPRO HD on a laptop without using proxies. This tech essentially eliminates much the bottlenecks associated with doing so.
It seems like Apple gimped the technology to get it out of the door quickly to compete with USB 3.0. For one, they're not using those "tiny" connectors, they're using mini display port (which isn't as small as something like s/pdif that uses optical)
