I know they did a huge proposal with Peyer and someone else to the Superman comic line. They were all rejected. 
Could that be it?

Comic-Con: Mike Mignola, Grant Morrison, Matt Fraction and other comics creators convene at EW's Visionaries panel

EW's own Nisha Goplan served as a moderator for the panel consisting of some of the biggest, most creative names in comics today: Jim Lee, John Cassaday, Matt Fraction, Mike Mignola, Robert Kirkman, Colleen Doran, and Grant Morrison. At this kind of event  where news and announcements take a back seat to questions like, "Why do you work in comics?" and "Who inspires you?"  watching these guys interact was half the fun. Whether it was Kirkman needling Morrison about his reading-in-the-bath(tub) habits (Kirkman: "Is that where you wrote Seaguy?") or Morrison asking Doran to go into greater detail about her Aquaman crush (Morrison: "Beard or no beard." Doran: "As long as he's slick.") fans got a chance to experience the personalities behind their favorite books.
Perhaps the most interesting questions had to do with the ways in which recent Hollywood exposure and interest has begun to change the medium itself. Some creators, like Morrison and Fraction, sounded frustrated that many now view comics as merely a stepping stone to film. Fraction pointed out that comics don't need to worry about silly things like physics or reality, so why follow the same cinematic rules? The best question, however, came from the audience: One person asked the panelists who they thought were the up-and-comers to watch; the Luna Bros (Girls), Jonathan Hickman (Nightly News), Jason Aaron (Scalped), and Derek McCulloch (Stagger Lee) were some of the names they offered.
And even though this was not the place for any announcements, a few telling pieces of info did drop:
1. In response to a question about the origin of the infamous six-page splash of the Batcave in All Star Batman and Robin, Jim Lee mentioned that he's working on a similar splash for the Gotham City skyline in a future issue.
2. Speaking of ASBAR, while it was originally planned as an eight-issue miniseries, it will now likely wrap up at 20 issues, Lee mentioned. "See you in five years!" he said.
3. Grant Morrison noted that he pitched a Superman movie last year, but it didn't take.
