Get ready for "your favorites from the past 14 seasons" to hit the Dancing With the Stars ballroom floor once more! ABC President Paul Lee just announced (while also talking about Happy Endings, Grey's Anatomy and Scandal—we'll get to that!) that Dancing With the Stars will have an all-star edition. But when? And who's in it? Lee just dropped scoop on ABC's just-announced new fall schedule, and here are the highlights you need to know: MORE: ABC Unveils Fall Schedule: Revenge and Happy Endings on the Move! • The DWTS all-star edition will air this fall and is casting now. "We can't talk about the casting yet but I would love to see fan favorites from past seasons come back," Lee says. "We have had many favorites. We're out casting now and I hope we come up with a really interesting cast our audience is passionate about." • Lee revealed that although a Hulk reboot couldn't come together in time for the 2012-13 TV season, the network is working on it for the 2013-14 season. ABC's parent company Disney owns the rights to Marvel, and Lee said they also have other Marvel shows in development, "but none that I can talk about at this point." • Revenge is moving to Sundays because, Lee feels, it's a perfect fit with Once Upon a Time. "Both shows have real cinematic ambitions," Lee suggests, while calling these two shows the biggest breakout hit dramas this season. In Revenge's old slot of Wednesdays at 10 p.m. is Nashville (starring Connie Britton and Hayden Panetierre) and Lee calls the move a "win-win for both Nashville and Revenge." Revenge will get a full 22 episode season and "you won't see as many repeats," Lee promises. • Grey's Anatomy is "still the No. 1 show on television," Lee insists, and sang big praises of Shonda's freshman series Scandal (holler!), saying what those of us who've been watching know: "Kerry Washington is brilliant in this one. The episodes are just getting better and better and better. If you haven't seen it please go watch on ABC.com."

And a final note for Marvel fans: The Hulk pilot was not picked up for fall, but the project continues to be in development and may be ready for the next development cycle, according to Lee.
