USB 3.0 vs Thunderbolt

Both technologies are from intel, and both are very fast. Fast enough to outrun even the fastest Solid State Drives. The fastest SSD I could find could write at around 650 megabytes, this is slower than the transfer speeds of both USB 3.0 and Thunderbolt. So really it is just like the Bluray vs HD DVD. My guess is that USB 3.0 will win because people already have the technology that will fit it. The only thing that I see changing that, Apple is already carrying the thunderbolt connector. That mean 10% of the market has/will have it, and 30% more will desire to have it. That is nearly half...
Now, although it can't be utilized, the thunderbolt is faster, and it can be even faster if the technology swaps out copper conductors for optical ones. But as a fast connection is only important in the case of a large file transfer, and you will be transferring between harddrives... it isn't going to get anywhere near that speed anytime soon.
