Ha! Ha! I'll tell you why Tero because just because they will be available on fewer discs doesn't mean that they will neccessarily be any cheaper. It just means instead of double disc sets they will be one allowing more room for bigger booklets AND the same for both the box sets AND any other box sets for t.v. shows movie series stuff of that sort. I think that that alone is a big deal mere less all the other freatures they will be able to have including the quality of film and sound to be nothing less than pioneering!!!
Believe me, I know that... Why else would a 5 cent DVD cost $10 in the store? Because both the artist and record company (or the television/movie studio) get a few $'s for every hour of material, and the store takes its cut on top of that.
And as long as there is that somebody to collect their share of profits, the prices aren't going to drop dramatically... What it comes down to in your suggestion is that EVERY Queen release would in essence be a box set of its own, and have a price tag between $50 and $100. :P
In theory it sounds like a nice thing to have more room for better quality programmes, but you should also remember that most of the Queen related material was never filmed with any better equipment than your average TV camera, which by 80's (or 70's!) standards means that it isn't even DVD quality, let alone HDTV.
