Not to you, but to many people it will. Porn and games push technology
I'd disagree with that, it's an old adage from the early VHS and Betamax days.
There was a lot of cries before the Bluray/HD-DVD war started that HD porn was going to win it, that simply wasn't the case though.
For one, Sony was quick to come forth in announcing they wouldn't be assisting Adult Film Producers in creating Blurays... though not banning them, just making it very difficult to get them produced. This was what Sony originally did with Betamax, they all out banned porn on the format, which is why the whole porn securing a format came about when VHS won.
This didn't happen with Bluray, it won outright.
Also Disney is one of the key contributors to the Bluray association and pushing the format... Disney won't allow their discs to be manufactured in any facility that produces adult content.
Thus porn really has nothing to do with Bluray winning, nor have I ever seen a Bluray porno anywhere.
Porn is quite cheap to make, 3D though requires the outlay on equipment and upping your resources... thus it boils down to whether it's really worth investing to shoot in 3D when a fraction of your audience is going to be able to view it in 3D, or for that matter pay to view it in 3D. I would imagine in most cases it's not worth it.
Games on the other hand, they make more money than the film industry now and really are the perfect media to actually see in Stereo. It's also got the plus that gaming is largely played solely by a single person right infront of the screen, which is ideal for the current generation of TVs that uses glasses and require you to be sat in a certain position.
