It is hard to say why did they stopped issuing deluxe editons of their albums. I would love to see some WM deluxe version. can they pull something related to their albums which were not "deluxed" yet from their vaults and it is not live stuff? I think they could.
but even stuff (Screamin Fields Of Sonic Love DVD and also two 80ties documentaries /according to Brian from WFMU who is doing liner notes for it/) planned to go for release next went on idle for some reason.
hard to say. probably busy with other stuff.
