Steven Moffat states that the Doctor Who 50th Anniversary will change the course of the series!

Fans have been watching the British sci-fi hit Doctor Who for nearly 50 years now but according to show runner Steven Moffat the Doctor's story could just be getting started. The upcoming 50th Anniversary special will set in motion events that will ultimately change the Doctor and how he travels about time and space. During an interview with SFX magazine Moffat stated that, 

"We’ve got to set the Doctor off in a brand new direction. It’s chapter two of his life. Now something happens to him that changes the way he thinks and the way he will adventure from now on. You can celebrate an anniversary in many ways – I think the most productive one within the narrative is to say “This is where the story really starts. This is where he finds his mission, he finds his destiny.”

He adds: “We’re not fibbing – this one is going to change the course of the series. And it’s very rare in Doctor Who that the story happens to the Doctor. It happens to people around him, and he helps out – he’s the hero figure who rides in and saves everybody from the story of the week. He is not the story of the week. In this, he is the story of the week. This is the day of the Doctor. This is his most important day. His most important moment. This is the one he’ll remember, whereas I often think the Doctor wanders back to his TARDIS and forgets all about it."

What do you think could happen to the Doctor that would cause him to go in this "new direction"? And what do you think this "new direction" could be?
