Yeha I can see no reason why there is a need for this kind of Vulgar muscle flexing by George Lucas. Seems kinda ludacris that he would do this when it would totally inconvience the movie industry. There arent many theaters that i know of that use THX or THX-EX decoding, as far as I know its mostly Dolby, DTS and SDDS (gotta love Sony), every projectionist I know thinks George needs to check his ego at the door. Besides for the average person there is no difference between 5.1, 6.1, 7.1 and 8.1 if its done properly. Its all just a "look what I can do" factor.
