Well actually Ishibumi said he hopes to see DxD get animated into a movie, even discussing with the anime staff. Also he considered Volume 9 for that but he felt that Volume 9 was better off a a normal TV series. But he (Ishibumi) says he wishes to do a movie for DxD.

Long story short, Ishibumi only said he wished for a DxD to get a movie but nothing to hint that there'll be one.
