Maybe it's true, maybe it's more prevarication. The 6-part JSA MINI-series written by Kevin Anderson is supposed to debut in August. In January 2004, Barry said in
a Pulse interview that he was *already concentrating* on the JSA. At a book a month (let's be generous), Kitson may already be done, or nearly so. In fact, it was reported on another board that Kitson started the JSA in 2003 and was now finished (not substantiated). The only other project we know about was the first two issues of Avengers/Thunderbolts, which were already published. The Empire mini ended in December. No other DC project has been announced for him, despite his exclusive contract.
Ask your friend to e-mail him back and ask him what he's doing after the JSA. He might get a more informative answer. Ask him also to specifically confirm/deny plans for a "Waid" Legion.
Ciao!
