I agree, Super- I feel like the show is really running out of fresh ideas. Turk and Carla are pretty much at the end of their storyline, Elliot is moving in by herself, Kim will come back just in time for the season to end w/ JD's baby. I don't really see what else they could do.
Plus, as much as I've enjoyed the "His/Her Story" episodes, it would be really weird not hearing JD narrate the show anymore.
