I actually couldn't care less about what his name is. A name is only a sound that is associated with a person. And Moffat can come up with any sound to associate with the Doctor. It's really meaningless.
It would only be shocking (to some) if it was something like Jesus. But, they won't be going there.
No, I'm much more interested in his backstory. His early days before he ran away from Gallifrey. The circumstances of him stealing the TARDIS (and the TARDIS stealing him). To me, that's WHO the Doctor is, and the answer to the question. Not a name.
