6. Value
It may seem dubious to call this a trend, but the fact is, the price of home theater products has dropped significantly while features and performance continue to improve.
Take projectors. Companies like Epson, Mitsubishi, JVC and others offer very good 3D projectors at half the cost of comparable projectors two years ago. On the high-end, companies like DPI and SIM2 offer technologies that eliminate the need for the additional expense of anamorphic lenses for viewing superwide CinemaScope movie formats.

The Epson 5010 projector is a good value for a big screen home theater.
Also a good sign: several home theater dealers now do a large portion of their business installing complete front-projection theater systems for around $10,000. It’s possible to put in a system for even less. The front-projection systems Huse offers, for example, start at about $5,000, which includes a 110-inch screen and the programming of a universal remote control.

I have my doubts that the trend toward small in the residential world is stoppable.

@Tuckertues, Most of the multi-screen rooms I’ve seen are for extreme sports fans, and I believe you’re right, it’s a variation of the “second screen” phenomenon brought on by smartphones, laptops and tablets. However, when you ask a person if they want to watch two games on screens the size of a notepad or on big TVs, the only decision is “how big?”
