From the U.K.'s Guardian:
Tennant's replacement will be unveiled in an edition of Doctor Who Confidential to be broadcast on BBC1 at 5.35pm on Saturday, 3 January, featuring an interview with the actor who is to be the 11th doctor in the long-running BBC1 sci fi drama, successfully revived by the corporation in 2005.
The best-known name the Guardian claims could take over the role of The Doctor is busy movie actor Chiwetel Ejiofor, the soft-spoken, self-proclaimed “monster” of “Serenity.” Ejiofor’s other credits include “Love, Actually,” “Inside Man,” “Melinda and Melinda,” “Children of Men,” “American Gangster” and “Redbelt.” A Black Doctor Who? i doubt the BBC would have the balls for that
