Pretty much. Though there's another batch not far behind them, ready for the Third Wave to launch after they get the ax. The Edge part of DC's line: going to be decimated. The solo League titles apart from the big guys---toast. The Dark looks pretty safe, except for maybe Demon Knights, which is toast the next time. Deathstroke---dead the next time. WWT? They're going to shoot that horse, I'm afraid. Hex got hexed.
Hex has always been a low seller in singles but does well in trade, so my guess is that WWT is safe. And it looks like Liefeld is moving over to Deathstroke, so look for that to die on its arse very quickly.
