They're not catching on as much as the industry had hoped. Once again, I think they had their hopes too high. People (including me, and I believe you too DAME), didn't run out to replace their high-def TVs with 3D sets, so sales aren't dazzling.
I don't think they quite understand that the big "DVD boom" at the beginning of this century was just like the audio change from LPs to CDs, or the switch from paper books to digital readers. It wasn't just an upgrade in quality, it was a changeover from analog to digital ... switching to a (somewhat) non-destructive, non-linear, and far more convenient format.
These other industry goodies like 3D TV or even the new 4K TVs are a format boost in quality, but they aren't going to revolutionize the industry or cause another stampede.
If old TV sets need to be replaced, consumers will probably spring for an upgrade to 3D or 4K as long as the price is right. That means slow but steady, trickling sales.
Blu-ray Disc and player sales are up from last year. Not by much, but they are up. DVD sales are down, which only stands to reason if HD disc sales are taking their place. And streaming is becoming a more viable and popular way to watch and store entertainment each year.
I'm not sure we'll see another massive boom or changeover in our lifetimes. Then again, I couldn't have predicted such a massive switch from analog to digital back in the day, either.
