So...let me get this straight...Swamp Thing is the bad guy and Alec Holland is the good guy? My prediction: Alec Holland becomes the new Deadman and Deadman becomes the new Swamp Thing and Alan Moore gets screwed over!
No. In yet another attempt to revert the DCU to the silver age and/or satellite era (depending on the character), Alec Holland (who never was the Swamp Thing as of Moore's "Anatomy Lesson" nearly 30 years ago) will be forced to merge with the plant elemental that is currently Swamp Thing, to restore "balance" to the natural order of life and death (or some such concept). Also look for some sort of forced attempt to tie "the green" (the Moore concept of plant energy) to rhe green light of Oa.
