Actually, this coming from DreamWorks, it should be in DTS's newest DTS ES DISCRETE 6.1 format, such as their upcoming The Haunting DTS ES DVD.
As decoded on the Denon 5800 (the first to offer this type of decoding), the center rear channel is 100% discrete and full range.
The newest edition of Widescreen Review goes into detail on how a DTS ES Discrete 6.1 master is born and how it is both a backwards and forwards compatible format.
And yes, any DTS decoder will work with this new format, it just reads the 5.1 core (with matrixed center rear) of the 6.1 datastream. The seventh discrete channel is packed in an extension file. When decoded as 6.1 Discrete, the decoder discards the matrixed center rear audio info. in the left/right discrete surrounds and only the extension file is heard in the center rear speaker. It retains 100% discrete, full range rear channels, unlike DD EX.
Music DTS CDs will start to support this too. The first is the title track on Don Henley's The End of the Innocence DTS CD (already out) and the entire upcoming album of Studio Voodoo (which was mixed specifically for 6.1 discrete channels and not a 2 channel recording remixed to 5.1 or 6.1). More to follow.
