Tangentially, I saw a report this week that some studios (Warner certainly, can't remember the others) are starting to sell current DVDs in China for $3 or so. They are priced to combat the 100% piracy level. They will have minimal packaging and no extras, but they will have the original English soundtracks.
When these discs leak out into the West (and they will...) then why would Joe Blow re-tool for HD/BD in order to spend $20+ on a disk that offers marginal improvements over the $3 version ?
