The Los Angeles Times has an article on the writers getting back to work after the strike, and how it will effect the up-coming pilot season here
It says about Dollhouse:-
"Gary Newman, chairman of 20th Century Fox Television, said the studio's development staff was in touch with its writers.
"We're not giving people hard-and-fast deadlines," he said. "We're just making them aware of the competitive advantage they'll get if they're able to turn their script in sooner rather than later."
Newman estimated that his studio had 50 to 60 pilot scripts in the works, including one from popular TV producer Joss Whedon, whose new Fox series, "Dollhouse," was ordered from a pitch two weeks before the strike began. Whedon is now busy writing both the pilot script and scenes for auditions."
So if Joss is busy working on Dollhouse, what, if any, effect would it have on the comics. Really "After the Fall" should carry on with Brian Lynch doing the writing. Joss has had his input in plotting it out with Brian, so, unless one of them come up with a brilliant new idea to use, it should be uneffected.
That leaves Buffy Season Eight. Of course Buffy always had other writers involved, and, as long as Joss has the guidelines about where he wants the comic to go, might have very little inpact at all. Or it could mean that they use more writers. It would be a shame if it meant the comic came out infrequently, as, at 40 issues, it is already a long undertaking. Missed months would be a blow to those of us following it!
