I imagine most video pros will want to stick with a MacPro for at least =
one more generation before depending upon Thunderbolt extensively.

I'm waiting for the next revision of MacPro before upgrading personally. =
Though i can see how iMacs and MacBookPros are becoming more realistic =
for intensive video work as time passes.

But those busses would probably have to be completely dedicated to that =

Taking that external without bottlenecking it is the challenge. The =
