I have no insider knowledge of this--I first heard of the Abyssal Plague when I followed the link, yesterday--I think people are forgetting one tiny detail:
Unless WotC is suddenly changing their plans, a metaplot can't affect the ongoing development of existing settings, because there isn't any. Three books and out, remember? So even if the Abyssal Plague is supposed to affect all the worlds--and from my reading, that's ambiguous--it will only do so via novels, and maybe DDI articles. The only setting that's really "ongoing" enough to have a metaplot is the core pseudo-setting of Nentir Vale & Friends. If it has any impact on the others, it'll have to be minimal, by definition.
