There is precedent for DC releasing a deluxe of a story even after releasing an Absi or omni. For example, The Invisibles got,a line of deluxes post omni, Ronin is getting a deluxe post Absi, Planetary got an omni post Absi, etc. I wouldn't give up hope for deluxes, but I do think you'll have to wait until the run is through being collected in Absi before you get another format for the series, and that could take at least a couple years.
