I highly doubt it means Physical and Suck, considering that the product description clearly includes them in the tracklist and openly acknowledges the inclusion of their 7 inch. I honestly think "secrets" implies the inclusion of the Broken movie, but we'll see. EDIT: Didn't see kleiner's response before I posted, same deal.
And while I'm aware that the main attraction of the DEs is having the albums on vinyl (which is more than worth it), considering that Trent said these releases would include "some surprises" (and the ever-vague "and more" description of TDS DE), the chance for contents the original vinyl releases lacked exists. In any case, affordable copies of these albums on vinyl is more than enough of a selling point on its own, regardless of what the whole shebang ends up being.
