"Angels Take Manhattan" Trailer

I got this delicious trailer for "Angels Take Manhattan" I am really intrigued to see what is going to happen.  I know it will be sad (for me)to see the Ponds go (I really don't want them to go);  but that is just how DW is and I think the next companion is going to be impressive. Of course there are a bit of spoilers so watch at your own digression.
