On the topic of Blu-Ray upgrades I'm just wondering, while I know MoC are a smaller operation, if some kind of a trade-in system like Criterion had/has* would be an option? As a proud owner of every one of your releases thus far I'd love to upgrade but it's hard to feel so happy about buying stuff a second time around. Especially in the case of
Une Femme Mariée, which I pre-ordered and received but haven't actually watched yet. Knowing my version is soon to be made slightly obsolete isn't the happiest of feelings. I know it's quite perverse to not be ecstatic about quality films being released in better editions but some kind of a trade-in system would make me, and surely others, much more comfortable in egging you on.
If I knew it was just a case of sticking the disc and the cost of postage and upgrade (whatever that might be) in an envelope and getting a brand spanking new Blu-Ray back in a week I'd waste no time joining the chorus to upgrade, well, to upgrade
everything 
.
*on that topic, does anyone happen to know if Criterion are still offering that trade-in deal? I'm presuming not but if it turned out they did it would change my packing criteria for my next trip to the US. After all, who needs clothes, right?
