There's also a question of whether such razzle dazzle gear is really worth the price, given the space in which people watch these films. I mean, if you designed a theater room itself, that'd be one thing. But just a repurposed room in a 100-year-old house or whathaveyou? That's probably overkill. Hell, I have a 9.2 Onkyo receiver and it's TOTALLY overkill in the space I have for my media room. I only run it in 5.1, due to the size of the room and the layout (no room for rear wall channels -- windows are there, albeit with blackout curtains).
So, I suppose the theater experience might be better in that respect, but is it better to a degree that makes me want to put up with everything else? No. I don't feel that I get sufficiently more value from that experience that I want to pay $12-15 for a single viewing in most cases. I'd go if I wanted to go see something and it had been out for a while (less chance of people in the theater) but otherwise, meh. I'll just wait til I can Netflix it.
--EDIT--
What I see as the shift is (A) a decline in theater attendance to the point where it's no longer profitable for the theater owners to operate (rather than for the studios to want them to exist), and (B) the studios gradually shifting to streaming content that they have direct control over, or which they have licensed to a content delivery service like Netflix or Amazon. What I'd expect to see happen is for Netflix (and its ilk) to either roll this content into its existing package and raise the rates, or offer a separate service for "First Run" films. The price would pay for Netflix's license, the studios would get paid, and the investment model would shift. It'd all be trackable, too, thanks to datamining, and those costs would be passed on to the content delivery companies (e.g. "Look, XYZ film was incredibly successful for you. We have the data. If you want XYZ:2 to run on your service, pay up.") who will eventually pass that on to the consumers, and the price, overall, will increase over time.
The key to this happening, however, is the theaters themselves closing up shop gradually. I see this happening at a faster pace than many might predict. Or rather, at an exponentially increasing speed. It'll start slow but then escalate dramatically as the theater experience becomes less and less pleasant. Eventually, that experience will reach some tipping point or critical mass, and that'll be the point at which theaters start closing a LOT faster. It might take a long time to hit that point, but I think when it comes, it will be swift and abrupt.
