Many new Hard Drives are FireWire today.
There are NO Firewire "adapters" for ANY amount of money, Firewire MUST be in the computer. USB can not "keep up" with Firewire port speeds.
There is not the possibility (from an engineering standpoint) of a USB to FW adapter of any sort.
Firewire is continuing to improve and gain in popularity. (Firewire 3200 will be out soon.) Firewire is more relevant than it ever has been.
Firewire is "isochronous", basically meaning that you can pump "clocked" data though it in real time. USB works more like TCPIP, with the data chopped up into packets and later reassembled. (Thus, at a minimum, you have latency, that is, the wait for the data to be "put back together".) Second, the Firewire protocol allows more direct address to memory (including mass storage) with minimal intervention of the CPU.
You could put the drive into a USB case.

There is a Thunderbolt to Firewire adapter. That should work fo connect your hard drive to your new Mac.
disclaimer: I have never used one.

The new iMacs just released have only Thunderbolt and USB ports on them....no Firewire. It doesn't have anything to do with solid state memory-based Macs like the Air. Just a direction Apple's chosen to go.
