It seems Scott Snyder is going to leave Swamp Thing , this comes as a no suprise considering he is going to write the new Superman series , along with Batman and from my source a new Vertigo title. Scott, you gave us an awesome run I hope the next writer is as talented as you are (maybe,Jim Starlin , considering he confirmed he is writing a DC title?).
Here are my sources :
