This poster claims he got this information from BBC America, I can't find it, so pinch of salt time, BUT they are probably about right. They are of course BBC America transmission dates, but the UK and US are supposed to be on the same day (unless the USA has another holiday lol :) )
Torchwood Miracle Day will end at the end of August or beginning of September...

Then Christmas Day for the Doctor Who special.
And of course there are the Confidentials etc.
And yesterday on Twitter is was confirmed that Doctor Who season 7 will be on in 2012, so don't listen to Private Eye (who where joking anyhow), or The Sun (who are f*cktards).
