I reckon all the other DC twice monthly titles will eventually follow suit and go back to monthly. Superman and Action did when Bendis took over and Green Lantern did with Morrison. The only one I see holding out (at least for a bit longer) is Justice League. It further solidifies those rumours about DC trimming its monthly publications.
But are they doing it to clear room for another publishing initiative ala New Age Of DC Heroes, or have they come to the conclusion quality is more important than quantity? I don't mind either way. Might actually benefit DC in the long run.
