I own the the lowest priced 32gig CF listed by newegg and I have never had a problem recording 8 channels at a time with it.  I've used even slower cards without a problem.  These CF cards are about the same price as the lowest priced SD cards.

UDMA 7 means that it will work great as a boot device. It's probably aimed at wedding & sports photographers for now, since they are the only ones who really need that much speed & capacity.

There's also the solid-state video recorder market that could benefit from increased capacity.

A bit expensive for those 128's right now, but the price is only gonna fall.
