Currently being advertised on Amazon.fr (their French store), is a DVD-Audio version of "The Wall". It is apparently scheduled for release tomorrow (June 23rd) but no other information is available.

We've not been able to turn up any more on this title, and assume that it is just a reissue of the DVD of the movie. No other retailer is listing this title, and as yet we've not been able to get any confirmation either way from Sony. As EMI seem to have gone for SACD as their multichannel music format of choice, it would seem unlikely for a DVD-A release of this title...
