I'm not sure if any of you read this but I'd like your thoughts. It's from Wikipedia. I've found it to be a very reliable source of information.
2009 and beyond
David Tennant is confirmed to star through to 2009. However, during the second half of 2008, Tennant is committed to a Royal Shakespeare Company production of Hamlet. Following the conclusion of filming for the fourth series, the 2008 Christmas special is currently filming.[11] After the Christmas Special, three Bank Holiday specials have been commissioned to air throughout 2009.[12][13] The programme will then return in 2010 with a fifth full series. Russell T Davies has suggested that the programme is expected to follow this pattern, of full series interspersed with occasional year-long breaks, for some time into the future.[14]
Soooo will there be an 11th Doctor when it returns for real in 2010?
