No need, X3 was a rushed mess but did deliver a few cool moments. Whatever happened, they can easily fix. Xavier returned post credits and the "cure" doesn't stick. So, find Scott wandering in the woods if needs be but things can get convoluted at that point. Playing catch up is never good for a film. There's no "Previously on X-Men" intros like the good old Fox Kids cartoon.
That would be the true test of a combo film or X4 for that matter. Resetting the franchise during the opening credits ALA The Incredible Hulk.
