I just read a very interesting article in our local paper about 3D HDTV, seem's like everyone was waiting to see how Avatar would do. A lot of people thought Avatar would actually be a big flop because of it's huge over exploded budget and all the big TV makers were waiting to see how it would do. You've also got Clash of the Titans and Alice in Wonderland doing very good. The article goes on to say that all the big producers and directers are now on board the 3D craze and we will be seeing alot of movies coiming out on 3D film and yes the main reason is money. The theaters feel they can charge more for 3D, 3D DVD's will cost more and of course you have all the equipment makers that will be making a ton of money. When you have movie makers like Cameron and Speillberg pulling for it, you know your going to see alot of it in the future. The author of the article also predect's with-in the next ten years technology will make 3D available with out the need of glasses, he points to the gaming craze and how it's advanced in such a small time into a multibillion dollar industry by graphics and 3D technology.
I myself see a big future in it, although I wish Hollywood would spend more money giving us GOOD movie's instead of fancey technology!
