Well...I have no faith in Moffat to address anything dealing with...well any of RTD's companions so I have to hope RTD rounds out the story himself because I don't want it to fall to Moffat. Yeah the last couple specials are going to be PACKED with stuff, but I think he knows what he means to do with Donna in them that will better finish her story.

I'm sure the focus will be on the Doctor given what we've been seeing, but that doesn't mean we won't see plenty of Donna.
