Courtesy of Ruther2 and SnitchSeeker, below is a video of David Yates briefly discussing his future projects. This took place at the opening of the Harry Potter studio tour. Yates says that filming is about five or six years away and that he intends to discuss the project with TV show supremo, Steven Moffat.
Personally, I think it's a bit discourteous and shows little respect to talk in the media etc about this movie without FIRST having discussed it with the Moff. And I admit, all this talk about a "reboot" and "starting from the beginning" fills me with horror. Why throw out 50 years of history? Still...lots of things can happen to scupper this horrible project.
