eh. You can't screw people forever. People want to watch movies in their homes. Theatre ticket sales are declining as dvd sales are rising. Meanwhile, studios are still paying ridiculous amounts of money to market films to consumers twice.
Same day home video release is an inevitability.
...that doesn't necessarily mean theatres have to go out of business. The most sensible route, as others, elsewhere, have suggested (and, in the case of Soderbergh's 'Bubble', implemented) is to charge a ridiculous amount of money for the DVD at first, and then drop the price of the DVD over time. That way, people can pay 8 bucks to see it in a theatre, then, if they like it, buy the movie for forty dollars, in the theatre, on their way out. Or they can wait several months and but the dvd at Target for a normal price.
edit: as for Spiderman 3, I am excited, but perhaps not as excited as I would be if the Spiderman 3 logo wasn't linked in my mind with the PlayStation 3.
