Running through to get to all the new stuff, ignoring the stories, sidequests, etc., 10-15 hours of play PER SIDE, that's 20-30 hours of RUSHED playthroughs. Take your time, keep playing, get all the goodies that pop up after you've "finished", minimum of 20 hours per side, probably closer to 30 or 40. Plus whatever NEW characters you build specifically to take advantage of the added content, and any subsequent characters. But, if you're playing just one character and plan on taking in the story, scenery, all of the new stuff, probably about 30 hours. Noth bad for $20 if you ask me.
