Sinestro Corps Special #1[Newsarama]: ...[Ethan] Van Sciver and [Geoff] Johns are reuniting for a 64-page one-shot in June that promises to take the Green Lantern universe to yet another level. Called Green Lantern: Sinestro Corps Special #1, the comic will explore and explain what has been teased for months within the pages of the ongoing Green Lantern series. Evil villain Sinestro, who hasn't been seen much since the pages of Rebirth, is gathering together an army of frightening characters and giving them yellow rings, then transporting them to the Sinestro Corps home base on the planet Qward. Why this is happening and what happens next will be revealed within the pages of the one-shot.
Newsarama has an excellent interview with Van Sciver about this project. Read it here.
