There is a listing for an untitled "X-Men" movie which must be "X-Men: Days of Future Past", but Bryan Singer is not listed as a replacement director for Matthew Vaughn. And since this "upcoming release listing" from 20th Century Fox goes into 2016, we can safely conclude that this list is current.
Once again, the only claim we have that Bryan Singer has been signed as the director of a multi-million dollar movie (after the failure of "Superman Returns"), is an endless barrage of press releases from him (and / or his publicity machine) that are always highly suspicious to begin with.
And once again, why is it Bryan Singer is always the only (former) theatrical director in Hollywood to make so many press releases so fequently? Joss Whedon, James Cameron, Ridley Scott, and Peter Jackson never feel the need to do it. Why does Bryan Singer always feel the need do it? Press releases that thus far have led absolutely nowhere for Bryan Singer.
Bryan Singer is claiming to be the current director of "X-Men: Days of Future Past", but we have heard this (all too familiar and overly played) song 17 times before from Bryan Singer....

It's a safe bet that "20th Century Fox" isn't even aware of the fact that they supposedly hired Bryan Singer to direct "X-Men: Days of Future Past." If a high ranking executive from "20th Century Fox" were to read this post, it would be news to them.
The world isn't suffering from amnesia yet...
