I too hope the rights revert back, but rather than another movie, I think DD would benefit more from a TV series. Not just a fun superhero romp like "Smallville", but a dark and gritty legal drama/crimefighting saga like something you'd see on FX or AMC. Rather than trying to cram all the cool bits into a 2-hour film, they could let the best elements from Miller, Bendis and Brubaker play out in a stretch, let them breathe and develop slowly over the course of a season.
On film, even if it's awesome, it would still seem like TDK-lite. But if they do a TV show right, DD could be "The Wire" of superhero shows, the one that every comic book show that comes after tries to live up to.
