From an amateur's point of view, it doesn't convince me.

I'll still go with Thunderbolt/FireWire.

I'm sure that no matter how fast USB gets, as long as it transfers data in the same way, it probably won't be ideal.
 
Blackmagic Design has a line of USB 3 I/O devices so USB 3 is faster enough to handle at least a stream of 10-bit uncompressed HD video.

Well that sounds promising, didn't even know they had one that records using USB. (I have an extreme that uses Thunderbolt)

Main reason I asked is i'm picking out my new computer and I wanted to know if I could use my USB 3.0 7200rpm external to record directly to, instead of picking something with an SSD specifically for recording high rates and then moving it to my external for editing. Sounds like I don't have to buff up the hard drive in whatever I get now...unless of course I want a peppy FCPX boot time.
