Three major Thunderbolt video interfaces made some big impact at the show.

Mark of the Unicorn’s HDX-SDI  will be out this summer and retail for around $1000. It’s rack mountable and features discrete audio interface for 8 channels.

Blackmagic also released a the Ultrastudio 3D for for around the same price in a much smaller package.

To me, AJA is the winner with their IO XT at just under $1500, theirs is basically a Kona card in a box that features meters on the front, 12v power supply so it can run off battery and most importantly (2) Thunderbolt plugs (the only one with this) to allow you to daisy chain storage and/or a monitor.
