Where is that quote from and could it have been written anymore shitty?
No idea where the quote above is from (Twitter I expect), but Danny Cohen (the controller of BBC1) has indeed announced that there won't be a full season of Dr Who in 2012.
This isn't the first time since 2005's return of the series that a truncated season has been announced. Remember, most of Tenant's final episodes were "specials" in 2009.
Remember also that the BBC is a public service broadcaster and there is a tight budget squeeze on it being imposed by the Tory-dominated coalition government. So it won't be just Who.
It's not as if the show is cancelled outright.
