That article, small that it is, doesn't say anything.
What they mean by B-R not taking up the slack is not that B-R sales aren't rising quickly, but that they are still so small when compared to the much older format that they didn't slow the drop by much.
This is like what we've read over the years about iTunes not stopping the drop in music sales. By this interpretation, iTunes sales weren't going anywhere, even though we know the were. Now, they're 25% of ALL music sales.
The same thing is true for B-R. Sales are moving up as many reports over the year have shown. But the base numbers are still too small to affect total movie disk sales.
It's also like Apple's computer sales vs the entire industry. The industry want up 2.5% this quarter, while Apple went up 17%.
So we can say that the PC industries sales were lackluster, and Apple's sales didn't change that.
Again, by this interpretation, Apple didn't see a growth in sales, when we all know that they had good growth.
Be careful of what's being read. Sometimes an article assumes the reader has other information, and when they don't, misinterpretation is common.
This is a little older, but it's typical of articles about B-R this year:http://www.tomsguide.com/us/blu-ray-...news-4250.html
