Guys info on AACS is around but info on BD+ is through 'word of mouth' only. Frankly the long technical specs on AACS is what the hackers used previously so quite why they put this stuff in open literature is beyond me. BD + guys are smarter here. I wrote a long post on all this when it blew up originally explaining the basics and I don't think much has changed. Basically BD+ relies on AACS and links into it, hence the fears over it's effectiveness, it is another 'link' for hackers to have a go at and I know some who see BD+ as the challenge to go for so personally I think it will last between 3 and 6 months tops (and I am supportive of the system). BD+ has undergone testing (rapidly) and there is an outside chance we might see the odd disc this year, but think early next year for most is more realistic I think.
