Jumping the gun?

Deadline is reporting that Fox 2000 has bought the rights to a projected YA trilogy written by Julianna Baggott. The series doesn't actually have a publisher yet, much less a release date or cover art, so I'm relying on the above article for a plot description:

"Pure is a dystopic tale about an apocalyptic event that creates two classes of people. The underclass consists of those who were scarred, and the "Pures" are those who were untouched and live separate from the others."

I'm assuming a movie deal rumored to be in the high six figures will be sufficient to get these books published... but it remains to be seen if the series will hit bookstores before the current craze for über-grim YA fiction dies out.
