I don't like USB 3.0. Thunderbolt and Firewire do it right. Video editing is done using Firewire. USB just has technical problems that make it inferior by design, even if it's supposedly super-fast.
What do you mean by "Video editing is done using Firewire" ?
I think we've moved past capturing tapes over Firewire.
You're right about Thunderbolt, though... there are quite a few tapeless capture and editing solutions based on Thunderbolt now.
But don't disregard USB 3.0 just yet. Cheap fast storage is always welcome. And USB 3.0 card readers are nice too.
