It's very simple. First: TEN YEARS LATER, and then a little boy runs up to a oceanside cliff, staring off into the horizon. Trailing behind him is Elizabeth, and the two stand watch as the sun sets. A bright, brief flash of green, and the little boy looks up at Elizabeth with this look. It's like, finally he really, really believes her. Then it's a close-up on Will, this small smile on his face as he spots them, spots his son for the first time. Annnnd...fade to black.

Yeah it wasn't much, but Mom and I were terribly disappointed by the conclusion to Will and Elizabeth's storyline (as it was when the credits rolled).
