Doctor Who 50th Anniversary: Predictions, Hopes, Fears

The 50th Anniversary is tomorrow! Do you have any thoughts on it? What do you think is going to happen? What do you hope is going to happen? What are you worried might happen?

Here's mine:

• Prediction: The entire episode (or vast majority) will take place in the Doctor's mind/history/living crack in time from Clara's perspective, because heavily abstracted metaphors are the only way the Time War can be shown without disappointing massively.
• Hope: Clara will do something to make her something other than Generic Essence of Companion.
• Fears: Clara will continue to be Generic Essence of Companion. The Time War will be a bunch of explosions.

This is a wild speculation post, so feel free to reply with your own ideas!
