Well, this will be an interesting case to follow....we will just have to wait and see what further steps will or wont be taken...
It's risky to make predictions, but I think that there could be a textbook sticker that would pass Constitutional review. It would be silly, but it could probably be done. Ken Miller's biology text has an introductory chapter on the nature of science, and what it means to have a theory, so it shouldn't be necessary for a book like his. But in Cobb County, they'd probably want to sticker it anyway.
