Warner did that only as a test to appease some people. They were never serious about DTS. Dave is right though. Don't be surprised to see Dolby 5.1 on the BR versions.
Since Warner doesn't support it(so far) and isn't a DTS fan, then I'd definitely NOT count on it. When it's lossless we don't need no stinking format war. It's all true to the source!
Regarding the flipper, I don't see the big deal. The extras which are extensive are on the opposite site. Also I would not expect Netflix to rent this. Color me surprised if they do.
Like they did with the last Ultimate Collection? :laugh: It never happened.
