I'd be surprised if the whole band would have been excited about playing the whole AA suite when Portnoy was in the band, and with him out of the band, I'd say the chances of them ever playing it straight through are slim to none, barring a Portnoy return years from now. It'd be a shame if The Glass Prison was tucked away forever, but I could see them avoiding all five AA tunes out of respect for their former member and the subject matter.
