It sounds like a memory card write speed limitation, is that correct? I've seen medium format cameras advertised with 5fps bursts (not sure on burst length), but if it takes 30 seconds between bursts to write to the memory card, that would drastically slow down the capture rate.

Exactly. The thing is, even shooting tethered with medium format, the pipe just isn't big enough to keep up and the computer and/or capture software gets bogged down, too.
