Just read on Bleeding Cool that the Rebirth run is ending in November with #83, with nothing out in December.
I thought the 750th anniversary issue in January was just going to be another name for issue #84, much like we had for 700/34, but now it seems to be more of a stand alone issue, akin to Action #1000 and Detective #1000.
Another clue that this may be true....Steve Orlando's first arc that begins in #82 was initially promoted as a seven issue story arc....now it's wrapping up in #750.
Is this all part of the G5 nonsense?
