I don't even see Jon releasing shows from the 2008-2011 era just because it'll make it obvious how much Jon's live vocals have gone down hill since then,why do you think he doesn't release any concerts from the band's prime years. Jon knows people will compare how he used to sound like in concert to what we have now.

Besides Jon has mentioned many times over the years,that he doesn't want the band to become a nostalgia act or a greatest hits band. The moment the band comes out with a DVD with shows from past tours, in Jon's mind he'll think the band has become a nostalgia act.
