I can see Venom, Wonder Woman, Black Panther, Moon Knight, Nighthawk, Catwoman, Green Arrow
Other than Venom, are any of these actually in the works? A few of those I find to be pretty far-fetched. Nighthawk--Why? Another Catwoman...!?!
As for Supes, I think TPTB would be happy if they managed to do Iron Man-level numbers, never mind the lofty records being set by TDK...especially since the next film won't have a decade or so of development hell written into the budget.
