That is the main problem. Price. Until prices are sensible people will hold off till they are cheaper or pirate them.

If I'm buying a new movie or series then I'll certainly have a very hard look at getting the BD version instead of the DVD. I'll only replace a film I already have in very special circumstances (for instance I'm seriously considering getting Firefly and Serenity on BD) but in general I'll stick with the DVD's if I already have them.

This is what I do (although my DVD collection was never that large). I never understand those who say they wont buy BD as they're not replacing their entire DVD collection. So don't. Keep you DVDs (and upscale them on your new fancy BD player) and when something new comes out that you want buy it on BD. Easy.

I try and do that, though the only things theat tend to get bought on BD are the films I really really want on BR or come in the triple play option. Otherwise it tends to be wait until the film is on DVD for £3-5.
