The movie has been in development hell for so many years, who knows when it will be out of it.
I think the next DC property to get a movie will be The Flash (not counting the Superman reboot or Batman 3). That's further along than Wonder Woman -- a couple of people are working on the script.
Plus, I suspect they'll wait to see if a network bites on the TV show. If the project gets picked up, I'd be surprised if they also move on a film; the poor box-office performance of Superman Returns was blamed in part on "Smallville." (Having said that, my inner comic book geek shudders at the idea of what David E. Kelley will do to a Wonder Woman TV show. And I thought "Smallville" set the bar for misinterpreting characters!)
