Re: X-MEN: Days Of Future Past (Casting, Rumors, Pics till release)
The Sentinels probably do exist in the timeline proper. We just haven't really seen them in the capacity they're designed for yet. Project Widewake was mentioned in the database that Lady Deathstrike stole in "X2". We know the US Government in the films have been attempting to have some kind of relations with the mutant community as Hank was the Secretary of Mutant Affairs in "The Last Stand". I assume that they will be unleashed in "X-Men: Days of Future Past" after some kind of present day attack. There was something mentioned about an incident in Paris...perhaps that triggers it. It seems certain now that Singer isn't totally ignoring "The Last Stand" so also perhaps the events in San Francisco will have changed the governments mind to take a more aggressive stance against mutants.

Ignoring the The Last Stand since 2011.
