They MIGHT skip DS9 and go straight to VGR as it was more popular
Huh?
I'm not so sure VOY was "more popular" than DS9. Ratings say otherwise. DS9 was first-run syndication - like TNG but less audience - but VOY and ENT were UPN shows, a fledgling TV network that struggled for viewer acceptance. UPN wasn't even received in some parts of USA. UPN's viewer numbers rarely reached the needed heights.
...assuming Blu-Ray does not itself get modified to support it, a new format will have a very hard sell on it's hands.
As it is Blu Ray remains quite small as formats go. Given the sheer cost to Sony of winning their format war they are probably pretty disappointed.
Last prediction I heard is that eventually no one will be buying physical media to take home and store on shelves. It'll all be "in the cloud", downloadable as pay-per-view, floating in the ether, waiting for you to tap into with your reception device.
Maybe but that's a way off yet. You need to have superfast broadband availble for everyone to make it work. But why would I want to say pay £3 to view something once, when I can buy a physical copy of it say at £20 and watch it dozens/hundreds etc.. of times.?
