Well at least the acoustic disc will be. This according to the latest Foo article in Rolling Stone. For those who don't know the latest Foo Fighters album will be a double disc affair called 'In Your Honor'. Featuring one disc devoted completely to rock, the other to acoustic material. I'm hoping that the Rock side is also a DualDisc (it would be foolish for it not to be as rock would sound more kick ass in 5.1 then the acoustic). Still awesome news none the less.
