I think Blu-ray is the format of choice simply because of it capacity.Blu-ray holds almost twice as much as Hd-dvd and that will mean something as movie are released in 7.1 or if studios decided to release movie series on high definition format.Hd-dvd is cheaper from a hardware standpoint, but I think as we inch closer to X-mas that will change.I still don't have either one, and I am not sure I will invest in one till they release all the star wars movies in hi def.
