That would be Van Jensen of Pinocohio, Vampire Slayer (and more famously, of PW Comics World) with a plotting assist from Venditti on Green Lantern Corps and Charles Soules of 27 (excellent comic, BTW) and having his first issue of Swamp Thing ship next month on Red Lanterns.
So one new writer to the DCU, another new-ish writer getting a second book.
What happened to Fialkov? In his own words:
Just a quick note to confirm what everyone knows, I am no longer the writer of GLC and Red Lanterns for DC Comics. There were editorial decisions about the direction of the book that conflicted with the story I was hired to tell, and I felt that it was better to let DC tell their story the way they want. I’m grateful for the opportunity and I’ll miss working with the entire Green Lantern team.
That’s pretty clear and up front.
While rewrites may not have been the exact issue here, you can spend an awful lot of time rewriting scripts (and not getting paid for the rewrites) if editorial changes their mind about where the story is going. It also can make it counter-productive to get ahead on your scripts, from the perspective of hours spent on a title.
