During the flashpoint event did they stop releasing current issues at that time until new 52 began?
Nope! New issues were still coming out. But they were almost universally filler content. Those last two months were all filled with stories written by folks who knew that a complete continuity wipe was around the corner.
Yep! I remember that. A lot of books on my pull list suddenly felt odd. It felt like either they were rushed or it was just random stories inserted in.
Part of it is that Flashpoint wasn’t ALWAYS meant to be a continuity wipe. It was just supposed to be a vehicle to get the newly-returned Barry Allen into the spotlight. When it was planned, the idea was that after it was all over everything would go back to normal. But DC decided to anchor The New 52 on it instead midway through production.
