I posted this in another thread in response to something Bradavon wrote, but I thought I'd copy it here since it pertains...
In case people are wondering why I care about profile 2.0 support so much:
With HD-DVD, they put deleted scenes and trivial tracks etc as downloadable features.
Some people speculated that this was done because of capacity constraints, but I think it was also done to promote the web-connectivity aspect of HD-DVD.
If anyone here ever frequented the "Insiders Threads" on AVS while the format battle was in full force, they know there was a Microsoft VP (Amir) who posted regularly.
He said one of the biggest challenges was trying to get people to look past DVD, and the way they were trying to accomplish that was by offering an experience that extended past the physical disc... basically doing things DVD wasn't capable of.
One example was being able to offer extra audio commentaries after a disc's release. Given that the HD-DVD menus are dynamically generated with HDi, it would have been feasible for a studio to provide an audio commentary for download, months after a disc was released, and it would be automatically integrated into the main-menu audio selections as if it had always been there.
So, it's completely possible that the Blu camp will do the same using BD-Live. Yes, many of the "proper extras" will likely be on disc, but I can see them withholding a certain amount of content to leverage the whole BD-Live aspect.
As much as many people have no use for it presently, it could be an important strategic tool in the battle to overthrow DVD.
And, in case some good content comes along (which I'm sure it will), I'd really like my BH200 to be able to handle it...
