DT is back in 2010 and 4 specials apparently, inless that was a double bluff, so people will think he cant have truely regenerated when he will. I think somehow, the master will make a return, there was a ring at the end of the 3rd finale that got saved. Anyone got any other ideas?

Jenny regenarated but kept her apperance. It might be that again so DT will do the 2010 series.
