What holds these formats back from really taking off is great titles, and the reason you bought a VCR in the 80's was because the OT was one of the first movies out there. The reason you would buy a Laserdisk Player was because you could get the OT in widescreen. Now it seems like you have to wait for these formats to mature to the masses, THEN we will see the big titles.
Just think if SW, Jaws, Indiana Jones, LOTR, Back to the Future were all out right now on one universal HD format, I would be Best Buy right now and saying bye-bye to DVD, but why would I want to even venture into a new format with two competing products, and only a handful of 'A' titles?
