Yup, not as bad as it sounded. Cheers to Moviehole who report the following:
All is back on track. A source to the film tells us this morning that a new ending does have to be filmed, but it’s all for the better. “A new ending's shown up on paper (or at least an outline of one) that makes sense and pays off”, we’re informed. The original just didn’t fit apparently, and Craven wants the entire movie to play out as cool as the first three quarters apparently is."
