It all follows in continuity with the previous movies perfectly.
Images show the Sentinels in the past. There's a still of one standing at Ronald Reagan's inauguration. The viral website also states 1973 as the year that Trask Industries unveils the Sentinel Program, and 2020 as the year when the Mark 10 Sentinel is created. So there have already been nine different Sentinel models by that point.
