I have no idea but walk down the aisle of your local HMV and tell me how big the Blu-ray section is in comparison to the DVD section.

Probably because HMV is a crap store. Most times when i have gone in there (my old local one) to get a blu-ray they haven't got it in stock. And the ones they do have, unless they are in one of their sales, are an extortionate price compared to elsewhere.

But i did notice before i moved that the DVD section had become tiny, while the blu-ray section had grown to about the same size as the DVD section. Don't forget, it was quite a few years before anywhere started stocking a good selection of DVDs when they first came out.
