Simon Pegg Rupert Grint Or....... Tennant.... again. On a side note, according to Moffat, a Timelord is still adhering to the "12 regenerations allowed" rule, which means this one is the last. I say last because if you haven't seen the most recent season finale, they revealed a "skipped" Doctor who is the real Ninth. That makes Eccleston 10, Tennant 11, and Smith 12. So we're looking for 13.
