I tend to think that we'll end up with a new team for House by the end of the season, but the original three will be back in the show as minor characters in other departments, sort of thing. I don't think it's in this show's style to completely restore the status quo... I mean, House lost Cameron once before, and DID manage to get her back, but the dynamic was changed because of it. I really wouldn't expect them to mirror this previous event again... so when they do come back (the cast list confirms that they'll be returning in some capacity), I don't think it's going to be on his team anymore.
