Yes, the developers have always described it as a "parallel universe" to the films. Here's one quote from lead developer Mike Goslin:
"We’re building a parallel universe, so we haven’t locked our game to a specific point in the timeline of the films. We want the world to be as thrilling and rich as possible and we thought the best way to do this was to draw upon all of the best characters, enemies, settings, and events regardless of their location in the movie timeline."
