This sounds like a 2-part question:
1. Since the Layla Anniversary Edition Set was a recent release on CD, and Audio Fidelity's primary market is Stereo CD and SACD fans, it would be too soon for an Audio Fidelity Multichannel SACD edition.
2. As to the "ever" part of the question, Eric Clapton is one of the most released artists in the Audio Fidelity catalog of SACDs. So it's easy to imagine a future Multichannel SACD edition of Layla in the future.
And that could include the 5.1 mix by Elliot Scheiner or the Universal Music 5.1 mix - depending on which one was made available by Universal Music, artist and record label licensing, etc.
Let me ask these two questions as follow-ups:
1) Most of us are aware that Audio Fidelity have released a lot of Eric Clapton-related albums on SACD, but all have been stereo, even "Ridin' with the King", which has a 5.1 surround mix, so did Warner Music prevent the surround mix from being used on the SACD, or was it Clapton himself that prevented it?
2) Since "Layla" was also released as a (stereo-only) High Fidelity Pure Audio Blu-Ray disc a few months back, would that complicate Audio Fidelity's chance to license the album and reissue it themselves?
