Sony use an HDD system on their top end cameras, so eventually it will trickle down. At the moment MPEG4 is waaaaaay below AVI, MPEG2 is a fair bit below AVI depending on the compression.
The beneifts will be: reduced size and quicker transfer from cam to pc for editing (no more RT capture required). BBC are developing a system called Jupitor, desinged to let many users edit from the same footage once it has been captured, with the HDD system the potential is there for editors to start work before the take has finished.
The prohibitive factor at the moment is the size of solid state cards.
To keep the current quality you would need a 12GB card for every hour dv tape.
Given that consumer HD is on the horizon, this requirement is bound to increase (the manufacturers consensus has been to store MPEG2 on DV cassettes, mistake!, MPEG2 is too efficient -ie lossy)
ANYBODY BUYING CAMCORDER TODAY, TOMMORROW, PROBABLY EVENT HIS TIME NEXT YEAR BUY miniDV. THERE IS NO BETTER FORMAT IN THE CONSUMER/PROSUMER REALM.
