I found it interesting that this seemed to be the first time PKJ talked of the WarWorld arc as something that will not be a status quo for the foreseeable future. He's talked about how him and Taylor had had discussions about Superman and Action crossing over in the future, but this was the first time he's indicated that the next "arc" of his run will be something that would be touching on Earth again in the context of Lois' involvement. I still think this is a Planet Hulk style run, so we're looking at a year or so of WarWorld, but he hadn't touched on that at all previously.
