QAM is use regardless, over the coax portions of the HFC plant.

The only meaningful question is this: In pre-IP VOD, do these "regional hubs" 
download their VOD content to a distributed set of servers, at head-ends 
throughout the MVPD network, or do individual VOD users have to send their 
requests way upstream, to the "regional hub?" If the latter is true, the system 
would be hopelessly limited. (Maybe they are hopelessly limited? You seem to 
say they are, but I'm not sure how true that is.)

IF legacy VOD requests go to a distributed set of VOD servers at head-ends, 
then there shouldn't be a big difference in network bandwidth required for VOD, 
whether IP is used or not.
