Hawkman got a brief mention at the DC Nation Panel this weekend in Toronto at Fan Expo. From CBR:
Didio added that they were trying to find the best, most recognizable and most popular versions of all of their characters, including Aquaman, Hawkman, Batgirl and Supergirl, who he noted only really works for readers and for the general public when she is "Superman's cousin."
Another hint about the return of Katar? Do more people really know Hawkman as space cop rather than reincarnated pharaoh? I suppose it's possible, what with Justice League lavishing a ton of attention on Shayera and Thanagar, and Katar's turn on The Batman. Hopefully something can be worked out so that Geoff Johns and David Goyer's take on the character can be preserved (Earth-2! Earth-2!) while opening things up for new cosmic adventures for the Winged Wonder(s).
As for Aquaman, I agree with rob! -- give him the Man Of Steel treatment coming out of Final Crisis and just go from there.
