Flashpoint #5. Because that's the only DC Comic coming out that day.
Here's what the solicitation text, released today by DC on their Source blog, says:"The war between the Amazons and the Atlantians has arrived. The battles between Diana of Themsycira and Emperor Aquaman will tear this world apart - unless The Flash can fix it! IMPORTANT NOTE: Because of its impact on the DC Universe, FLASHPOINT #5 is the only title that DC Comics is currently soliciting to arrive in stores on August 31."
I plan to be reading it, as the first issue really hooked me in what was probably the first Barry Allen story I ever really cared about, except for maybe the Crisis on Infinite Earths issue where he died. I'll talk some more about it in our What Are You Reading? feature this weekend, but this particular first issue was a winner in my book.
But I wonder what could possibly happen in the final issue that has DC pushing everything else off the schedule?
