I say both., that DTS ES mix is unique and is worth preserving.

Is the Cinema DTS track the only source for the original theatrical mix? Is what appears on the Blu-ray a near field mix?

I agree! I believe that the audio heard in the cinemas was a DTS-ES mix as well, but I could totally be wrong on that.

I haven't actually watched the blu so I have no idea what that audio sounds like, but I would assume that it is indeed a near field mix. The DTS-ES mix on the original DVD is an aggressive near field mix (but not too over the top, IMO) and is most definitely demo worthy.

I wonder if the audio from the blu is simply a high-resolution version of the DTS-ES mix from that DVD... or if they did another remix.
