Matt Smith deciding to leave the role has let alot of people talking about that person being the thirteenth doctor. which could become the Valeyard... it's strange. and no knowing what to do.

The main one that jumps out at me that wasn't depicted was the Eighth Doctor's (Paul McGann) regeneration into the Ninth Doctor (Christopher Eccleston). Were there any others that weren't depicted? I think I remember most of the rest...

The transition from the 2nd Doctor to the 3rd Doctor wasn't a typical, on-screen regeneration and there's a gap between the 8th Doctor and the 9th Doctor... But I'm gonna guess that John Hurt is going to be either before the 1st Doctor (as we know him) or between the 8th and 9th Doctors. The oddities between the 2nd and 3rd Doctors don't strike me as significant enough to accommodate an entirely new incarnation of the Doctor.
