Well that would certainly bring a new way to enjoy these films. I remember an article awhile back that quoted Lucas, Cameron & ?? about a way to bring 3-D to the masses. I think at the time box office $$ was down a bit-losing a battle with home dvd.
Not sure about the 3-D thing but I would certainly go.
But it's also true that a high quality film, no matter what the medium, will bring in revenue for theaters.
