Here's what Moffat said about Rose, which sums up why I'm ok that Rose was absent:
"I thought the story of Rose, which was beautiful, was done. I didn't want to add to it, I didn't feel qualified to add to it. That was always Russell's [T Davies] story. The way Russell ended it in The End of Time was perfect. I didn't want to stick another bit in. It would be wrong. But we did want Billie Piper, one of the absolute heroes of Doctor Who, back in the show without interfering in the story of Rose Tyler. I think I might of spoiled something if I had done that."What Moffat said about the upcoming Christmas special:
"It's a proper finale to Matt Smith, it's the story we've been telling since he put the bow tie on. A lot of stuff we've left hanging, we tie up there. And it's Trenzalore!"Soooo basically, take all my predictions and hold onto them for Christmas. Except also add in the hope that they'll place the 50th in there as well, in terms of continuity. Because CONTINUITY, DAMN IT.
