Interestingly, DC's big event, INFINITE CRISIS, also fell behind by a few months, but that was during the final leg of the series (the last 2 issues or so). CIVIL WAR, in contrast, is at the midway point and the delays are already starting. Any way you slice it, that isn't good news.
Of course, considering the constraints of the medium, a 70 chapter crossover series was bound to have problems. Countless Marvel books, some not nearly as pivotal as CW, have been plagued by delays. But, I guess Marvel hoped for the best with this overlong series.
Hopefully, the rescheduled issues won't bombard otherwise slow weeks with wallet-busting amounts of books. That happens sometimes.
But honestly, CIVIL WAR has become sometimes overbearing with their arguements, which we have heard a million times, and makes no secret about "which side is right" and all. So a little break may be good. It's unprofessional, but that's Quesada's middle name. If not, it should be.
