In that case just forget the 50th altogether! Just wait until 2015 and do a 10th anniversary for "New Who" since you obviously don't care about what has come before!
So what you flash some still images of past Doctors in a 4 second montage?!?! I've been watching the show for the past 35 years and I CARE about what has come before.
If RTD and Moffat spent LESS time on "Awesome, epic, all-encompasing story arcs" and just got back to some stinking traveling with a companion and stumbling into situations where you can help...... Well, that's the Doctor I want to see again!
Half a dozen people have posted ideas on how to make a 50th with ALL current past Doctors (myself included) that would explain their current age and how it fits in, that would have been GREAT ideas for the show. (Mine dealt with the multi-verse theory where other universes exist in which some Doctors had not yet regenerated into their next incarnation, so we could have Tom as an older 4th Doctor, Pete, et. all. and since they exists in a different universe, it works. The universes are collapsing and the very fabric of space is unfolding. The Doctors of all these universes must work together to save it before the collapse, then afterwards, they all go back to their home. Matt turns to head back to his TARDIS, but takes one final look at all of their TARDIS' leaving, turns to Clara and says...."In the words of an old, dear friend, Lovely Chaps, all of them!")
We could have had such a great story, but instead we're getting Time War - Victorian England - Far Future, a Doctor we never knew of, and Two main monsters..... all in 75 minutes!
I'm sorry but this combined with the COMPLETE LACK of a PROPER 8th series is dreadful!
I may change my mind in a couple of weeks, but right now, instead of gleefully anticipating it, I'm more pissed off about what it will NOT be!
