[L]ike DPLIIz and DTS Neo:X, Auro-3D can supposedly function as both|either a (single ended) "blind upmixer", or discrete encode+decode process, with the encoded content still backward compatible PCM 5.1.
[So if Barco gets a decent installed base of Auro-3D decoders|expanders into large screen 3D venues in the next year or two, I expect Cameron wouldn't hesitate to add an Auro-3D encoded version of Avatar 2 -- having previously gone to the effort of creating 18 different 'versions' of the first Avatar movie for the domestic market alone! ]
However, it seems that an Auro-3D encoded movie soundtrack is already being mixed for theatrical presentation according to this quote from page 68 of the September 2011 edition of Pro Sound News Europe:
So now I guess we have to wait until January 2012 to discover which "triple-A Hollywood movie production" is being hyped here!Quote:
'In autumn 2011, Barco will install an Auro-3D system in reference cinema theaters worldwide – one in each continent to start with – which will act as pioneer venues for 3D sound. “In January 2012, a triple-A Hollywood movie production will be released with the Auro-3D format,” enthuses [CEO of the Galaxy Group, Wilfried] Van Baelen.'
