It was bound to happen eventually. DC Comics just announced the first New 52 books to be cancelled.
The following DC NEW 52 titles will be cancelled with issue 8:
Hawk and Dove
Men of War
The following new books will replace the cancelled books:
Worlds Finest (featuring Huntress and Power Girl)
My quick thoughts:
I love OMAC and Blackhawks and really hate to see these go.
I hate the Batman Inc storyline, but I'm in love with Dial H for Hero.
Why not yank Firestorm and Savage Hawkman or Captain Atom and keep OMAC?
