Deadman in the upper left. Martian Manhunter isn't even mentioned in the article. Manhunter will be in a different team.
And I hate that little fact. Just because I'm such a sucker for MM, I buy another team book I'm otherwise not that interested in. How come Deadman and Mera are in, but J'onn, one of the founding members in ANY chronology (yet), is out?
It would make much more sense--story wise--to not have Batman, put him in StormWatch. Martian Manhunter IS the League.
