I'm going to wait and see what "Gotchas" the new players have.... If the copyright management is too draconian, or the pricing isn't there, I'll stick with my DVDs until a clear winner emerges.
I still haven't bought a DVD Audio or SACD player since I can't play them anywhere but home. It has to work in my computer and car stereo or I'm not interested...
With DVD is different as I only watch movies at home or on my portable DVD player. They will have an easier time of convinceing me. I usually jump in when the machines hit $299 which should be about 12 months in, but ONLY if they don't crazy (the rumor that they will disable hardware that plays any pirated discs by loading "keys" to the machine or via an internet connection will keep me out of the pool. Ditto if they downrez to anything but a component connection. MY TV only has 1 DVI connection which my satellite receiver uses. It has to work over component video or I'm not upgrading)
