I have decided that when I build my theater I am going with Dolby/DTX setup (SVS Prime elevations for the rear heights!) but I am most excited for the other possibilities of object based surround sound. Hopefully one day we get systems that measure the actual speaker placement, but I am sure we will get interactive broadcasts & movies (home or away announcers for sports, crowd noise on/off, a functional directors commentary feature etc) through this technology.
