Meh, never been a fan of John. He's the Lantern with the least personality. If this is true, and the new creative team follows through, I won't be too broken up.
I've been a fan of John Stewart since Cosmic Odyssey
when his hubris led to the death of an entire planet. Early 90s John Stewart was a pretty compelling character when he was working through the repercussions of his arrogance.
