So I guess, the online speculations have started. David Tennant was recently asked about his involvement in a possible anniversary multi Doctor special. The answer was what can be expected at this point. I am guessing we will be on the 14th Doctor by then. Although it’s possible that Jodie is still the current Doctor. Could the anniversary be her regeneration maybe? Could we expect a team up with the 8th Doctor, finally seeing him again in a full length episode on screen?
