Simon & Garfunkel Reunion CD. DualDisc coming?

[JonUrban]

I got this 2 CD set for Christmas, and in the CD booklet is a 5.1 mastering credit. I know there is a DVD of this concert which is probably done in 5.1, but I wonder if a DVD-A or DualDisc was/is planned of this recording? Odd that they would put a 5.1 mastering credit in a CD booklet! @:

Has anyone heard anything about this possibility?
