Green Lantern news is always Nice. Hope this actually happens.
This is what Guggenheim had to say:

“I’ve been working my ass off on Green Lantern,” he said, then laughed. “I’m ready for a weekend off. I really can’t say too much about it. I’ve sworn a blood oath of secrecy. I will tell you it features Hal Jordan and is an incredibly faithful rendition of the character. It honors everything everyone loves about the hero. We approach it from a fan’s perspective. Every step of the way, we ask ourselves what we want to see and what the fans will want to see. I think we have a script that will actually satisfy on those levels. Right now I’m just doing a rewrite for the studio with Greg [Berlanti] and Michael [Green]. We’ll turn that in next week. We just keep moving forward. It’s really good stuff!”
