Thanks to commenter Ryan, we have the following little tidbit from Bleeding Cool via the DC Retailer Summit:
...DCU Presents, Green Arrow and Hawkman are picking up where Brightest Day left off.
Which is not surprising at all. I would add Firestorm and Aquaman to that list, most likely, from what we have seen from the early information. And as I said, its not surprising at all considering that Johns sketched all of these arcs out for the Brightest Day guys (and Krul wrote the BD stuff for Green Arrow). Again, as I have said before, I wasn't sure about how to take Hawkman after the end of Brightest Day, I am glad that my initial concerns of "why did I buy Brightest Day?" are evidently baseless.
Also interesting to note:
Most of the released solicitation images for the DC Relaunch are not the covers for the first issue – so look forward to all those being announced soon as well.
Interesting! Some of those more iconic images not being the covers to the #1s is a strange approach, but who knows? Maybe the actual covers will be even more iconic.
Thanks again, Ryan!
