Couple of things:

1) Do you have a source for this poster that isn't tumblr (unless its the official DW tumblr)? That's the only place I'm seeing it and I have a very hard time believing the BBC are advertising the finale when its 9-10 weeks away.
2) It doesn't really reveal anything. Even if it is a TARDIS she could be the Rani, another established Time Lord or even a brand new Time Lord. Hell she doesn't even technically have to be a Time Lord to have a TARDIS I guess.
3) Those phone booths aren't actually that old, there's still quite a lot around.
