@tsarstepan,
The home "3-D" DVD is more likely to give one a headache than entertain. We'll have to wait until next year when true 3-D capable displays become available but it's going to be the same problem, besides coming onto the retail market with a high price tag, than hi-def DVD -- lack of software (compounded then by two opposing formats -- HD DVD and Blu-Ray). Although the gaming industry is likely to go nuts with it.
With 1080p films on a good home theater video and sound system, the theater has become a less frequent outing for adults, especially someone with a family. The popcorn savings alone is enough to buy the DVD.
Especially since restorations are beginning to be released in Blu-Ray hi-def like "Becket" which actually look better than their theater projected counterparts.
But the dinner and a movie date will likely never really die.
