Well I hardly see Donna coming back seeing as that was RTD's character, and Moffat seems to have a good handle on creating his own characters which is a good thing. Plus, who wants the same characters always coming back, just look at how they ruined Rose when she came back for the series 4 finale, she went from a normal person to being a super action hero of sorts. I think we're all tired of seeing them crank out Dalek episodes so just image how they could ruin characters in the same way.
However, if any character should come back it should be Jenny, because she was pretty awesome.
I hope Romana doesn't come back as River Swan, because well that would just be sort not too exciting at this point, though it'll be a lot more boring if it is the doctors wife. Though, if he's as good a writer for DW as he was for Coupling he won't have that happen.
On a side note, glad to see there's no Matt Smith hate on here, cause well he is rather good and doesn't mope around like the 10th doctor was made to do (for three seasons and a set of specials) especially crying that he was going to regenerate, RTD really made that show into a soap opera at parts (still there were more than enough good/great episodes to make that not take away from the show).
Does anyone else notice how the stake in the front of the UK section of Epcot sorta looks like the stake in the center of the town in The Android Invasion (if you don't know the episode you are not a true fan).
