Reddit mentions of Wonder Woman by George Perez Vol. 2

It's very possible this listing is incorrect. It wouldn't be the first time Amazon has had a listing for a second Perez omnibus that never came into fruition.

Originally, when the second George Perez Wonder Woman TPB was solicited, it was solicited as a second volume Perez omnibus. That ended up being a mistake, and quickly being changed to the second paperback. That was about a 6-8 months ago.

DC's trade catalog was released through May 2017, and a second Perez omnibus was no where in it.

All that said, there are some signs that point to this book finally being real. For one, there is solicitation text specifically mentioning that Perez's entire run is getting collected (the previous listing just had generic text about Perez himself). The fact that it's a separate listing from the second paperback is a good sign (though you should always take an Amazon listing with a grain of salt because it's incredibly easy to get a listing put up there with incorrect/misleading information). Here's hoping it actually happens!

EDIT: THE CATALOG WAS UPDATED AFTER IT WAS RELEASED and a second Perez omnibus is now listed in the catalog!! It wasn't originally in the Spring 2017 catalog!

However, I must advise patience. As I said, this isn't the first time a second Perez omnibus has been announced. Hopefully, with the movie so soon after, the book will actually come to fruition this time. We can hope!
