One industry fans of 3D Video in the home should watch, in a purely business-like way of course, would be the Adult Film Industry.  Working with significantly smaller budgets than Hollywood or video game studios, and suffering a complete lack of large-theaters for showing, they rely entirely on 3D in the home.  One director in the industry had this to say (and I’m sure he intended that pun in his quote):

“We’re very excited to do 3D production, but we don’t feel market penetration [of 3D TVs] has hit the level we need it to be in the home,” said Rob Smith, director of operations at Hustler Video Group, in an interview in Las Vegas. “I’m hoping by the fourth quarter of this year it will be at the point where we can justify doing a 3D product,” he said.

What do they think is the biggest hurdle to overcome?

3D glasses are also an issue, he said, because people don’t want to be encumbered by eyewear when viewing a film. “I think the glasses are the barrier,” he said.

When viewing a film, or engaged in…  other activities.
