Yeah, from what I've heard, some time in 2014.When in that year, I don't but based on previous experience, it kind of depends on where you are. It will come out in England faster than in the US. That's all I really know.
No date has been set yet, but the FILMING is set to start in the beginning of 2013. It will be a long wait, but we made it last time, right? And it will be worth the wait.
//We are the fandom that waited//
No clue. :(
Yeah, it has. There are three episodes in each one. In the 1st season, there's "A Study in Pink", "The Blind Banker", and "The Great Game"; and in the second season, there's "A Scandal in Belgravia", "The Hound of the Baskervilles", and "The Reichenbach Fall".
The third?? The second season hasn't even come out yet... at least not in America D:
