Except, the print runs were set quite a while ago, to ensure the 3D cover production process.
As we reported earlier, Dan DiDio announced to retailers that some of their orders would be heavily allocated, so they won't get everything they ordered. And for those thinking they can massively increase their orders this week to get a greater allocation, I understand orders will instead be based on previous orders for different titles.
Reprints of the 3D covers will be coming in November and, as with the Justice League Of America state flag variants, retailers will be able to order a boxed set of all the covers then. And retailers will be allowed to order non 3D cover reprints this week if they need to make up the numbers.
Expect to find out more later today.
