Theres no firewire in the new iMacs?? I have 4 ULN-8 audio interfaces from Metric Halo. These are $6k a piece, and are FW 400/800 only... Will I seriously not be able to use these with new iMacs? If we decide to upgrade, or a client has an iMac, are we SOL? Sorry, I'm just surprised... hopefully there will be a workaround. http://store.apple.com/us/product/MD464ZM/A ?
