The Sentinels will be in the future, that is the threat Magneto mentioned in the mid-credits scene in TW.
It all follows in continuity with the previous movies perfectly.
You are way, way off in your understanding of the timelime.
Here, take a look at the Trask Industries website, which will show you that the Mark I was released in 1973, way before The Wolverine! And, like I explained, since we've been shown the timeline in X1-3, First Class, Origins and The Wolverine; we know that the Sentinals do not yet exist in the timeline we've been shown. So for the Sentinals to be released in 1973 something MUST have changed prior to that time, affecting the timeline and possibly changing everything and anything from that moment on!
