So Standard 1.1 isn't even out and confirmed yet and already this apparantly confirms to v2.0... that's impressive.
As for larger discs, more sold.... 10:1 players sold (as Sony count every single worldwide PS3 player as a BR player sold despite in a survey over 40% not knowing it can play DVDs!) yet only 2:1 discs.... check Amazon at the moment for the top selling units.
As for better interactive and more features/content... some of the reasons cited by Paramount/Dreamworks for the recent HD DVD exclusivity was the fact that additional content is a nightmare to write for BR and far more resource and capacity hungry (check the 300 disc for example... where are the features on the menu etc that make it a better use of the extra 15Gb of capacity - there aren't any, the HD disc is a better copy, the extras are better, it actually has online content.. need i go on?)
Go back and look at early quality BR discs, i've seen better from SD, and that's before upscaling....
I think as with most things Sony, BR will die the quiet death, especially as they've now stopped subsidising the pressing, which rumour has it costs more than twice that of HD as Sony own the rights to materials required.
The basic failing for Sony was a lack of standardisation from the outset, HD DVD had this from launch, so all players/discs conform and with firmware upgrades will be able to play any HD disc made from now on.... when 1.1 (god knows with 2.0) of BR comes out, all current players will be unable to utilise the advanced features - such as online content and thus will technically be rendered obsolete - genius! Where do i buy into this sound investment?
