... how many HDTV owners are actually watching HD?
That's actually a non-rhetorical question.
If you re-formulate it and ask "How many HDTV owners when playing DVDs know/notice that it is not HD?"
I'd be really surprised if the answer were anywhere close to 50%.
To get a proper 3D setup at home you have to:
- have a 3D TV, i.e. bought one in the last 6-12 months or so;
- have a capable BD player (same time frame);
- have everything properly connected;
- have lots of patience to make this work (HDCP, DRM, etc.)
[Or you can have more money than brains but that is even a smaller cohort of people and therefore can be neglected.]
Considering the annual sale of BD discs is 25% of DVDs if not less, 3D versions are probably less than 10% of that.
Bottom line: for a new standard to succeed a critical mass of users has to be formed.
BD can hardly be called "widely adopted". 3D even less so.
Hopefully it won't be killed. And one day it will be (mostly) done properly and won't cost an arm and a leg to experience.
