Bryan Singer returning to X-Men?

You may have read that Bryan Singer mentioned this possibility in a recent interview.Here's what i wrote on the subject (in my review of Wolverine):

"What i would want to see is X-Men 4, a true sequel to X3.The reception to The Last Stand was lukewarm and many think that the series reached its peak with X2, and so it's argued that there is no reason for another sequel and if there was possibility for such a movie, new contracts with the actors and actresses would be needed, which means new negotiations and maybe higher cost.However, i would like to see, after some spin-offs, a true X-Men sequel, ideally with most of the cast and Bryan Singer returning.I think that there many good stories that deserve to be told.I know that it's probably not going to happen, though you can never be certain for anything."
