as for Thunderbolt becoming like firewire, I doubt. firewire was apple's only while this is intel's.
Firewire was Apple's name for IEEE 1394, an industry standard. It was never Apple's only, as its creation was a joint venture, and openly licensed. It is actually cheaper to license IEEE 1394 than it is USB, but the silicon costs of implementing USB are far less.
USB and Bluetooth both caught on because, in large part, they were designed from the ground up to be implemented with very little die space, and thus be very inexpensive to build. Just as ATA/ATAPI quickly kicked SCSI out of mainstream PCs for the same reason.
I don't know the details, but hopefully the Thunderbolt team learned their lesson as the specs look great. The Firewire team clearly didn't. Technological superiority doesn't matter if your competition is "good enough" and cheaper.
Even if they didn't learn their lesson, something better will replace it shortly sending more shivers down a nerd's spine. ;)
