The Diamond Comics Advance Reorder List is a great speculator tool. It shows what books retailers are going back to get more of, in advance of their release. They are actually putting their money up betting these books get big. These are the books people are talking about in shops, message boards, and websites. Here is the Diamond Comics Advance for 8/13/17:
It is all about the lenticular covers. DC has two on the list with Action Comics, and Marvel has one with Legacy. Calexit sneaks out of nowhere and appears on the list for three separate issues. Secret Empire 10 makes a couple of appearances as well. The random books include Metal (great 1st issue), some trade paper backs, and that is about it. Check out the full list below.
