It's been almost two years since 'Sherlock' has been aired and fans are still waiting for an official air date for Season 3. While initial rumors suggested an October or December release date, both theories have been debunked, as the show is still in the post-production phase and producer Sue Vertue took to Twitter to debunk a Christmas special. As such, the current accepted theory is that the show will return early 2014. Fans can also rejoice knowing that Season 3 will not be the final season, as both Martin Freeman and Benedict Cumberbatch have displayed interested in taking part of Season 4. "We've agreed to two more series but I could get into trouble for saying that," said Cumberbatch when asked about a fourth season. But that's not all! Apart from the most likely air date and the confirmation that there will be a fourth season, we have 13 leaked spoilers for you from the upcoming season: RELATED: Is Moriarty Really Dead? Find Out How And Why The Character Returns
1. Season 3 will be the best season yet. "It's great. The second series was weird. Because it was such a phenomenal success, we were a bit distanced from the routine and the inhabiting of those characters," explains Cumberbatch to Hypable. "This season, straight into it, comfortable. And [the characters all] immediately fit under our skins. Really hard work because it wouldn't be a good show unless we were trying to evolve it and set ourselves new challenges and standards. But I love it. I'm very fond of playing him. You're in for a treat this series." 2. The season will focus on Sherlock and Watson's friendship. "It's when John and Sherlock meet again. I think that's the showstopper," he said, adding that the season will show how the friendship has changed with Watson getting married. "It's a long, complicated, emotional journey, and extremely funny." 3. The reunion will be dynamic. In the short stories, Sherlock disguises himself as an elderly book seller so he can get into 221B Baker Street before revealing his true identity. "I always found it a little unlikely that Dr Watson's only reaction was to faint... as opposed to possibly a stream of terrible swear words," hints Gatiss.
4. Moriarty will be back! But as a corpse. Fans have long been wondering if Moriarty would have also faked his own death, but Moffat has turned down the notion of Moriarty being alive. "He can't come back from that," Moffat said. "He shot himself in the face. What more do you want?" 5. The new villain is revealed. Played by Dutch actor Lars Mikkelsen, the character of Charles Augustus Magnussen will be Sherlock's new nemesis. He will be introduced officially in episode 3. According to the short stories of Sir Arthur Conan Doyle, the nemesis is introduced as blackmailer. (RELATED: 4 Things To Know About The New Villain)
6. How Sherlock survives his fall is revealed. Sherlock is seen throwing himself off St. Bartholomew's Hospital in the end of Season 3 but the last scene shows Sherlock is alive and well. "How did he survive the fall?" Freeman said. "All the clues were on screen. It's not going to be a cheat -- everything that we saw on that final episode offers hints as to how he did it."
Viewers saw Molly Hooper being asked to help, hinting that she helped Sherlock fake his death. "There really are only a few ways you can fall from a roof and survive," said Gatiss in the San Diego Convention Center's Ballroom 20. "It's not black magic."
7. Sherlock has been hiding in plain sight. "He actually has a line in [series one finale] the Great Game which is 'The art of disguise is knowing how to hide in plain sight' and that was because, right from the start, I thought modern day Sherlock Holmes would not put putty noses on, he would basically be standing behind you now and you wouldn't know he was there," said Gatiss.
8. Love is in the air for Watson. Dr. John Watson will be getting married in Season 3 to Mary Moirstan (Amanda Abbington) and Sherlock will be his best man, according to the show's creative team. "Hot off the presses from 110 years ago, John does get married," joked Moffat. "We hoped that you wouldn't sneak ahead and read the books."
Incidentally, Abbington is Freeman's real-life girlfriend. "Working with Martin on 'Sherlock' is really quite inspiring, 'cause he's so good at his job. And he and [Benedict Cumberbatch] have this fantastic chemistry," says Abbington. "Coming into 'Sherlock' you have to up your game, 'cause they're so good together." 9. Sherlock won't find love, and he's okay with that. The show's creative team revealed at Comic-Con International earlier this year that Sherlock won't be finding love any time soon. "Sex for Sherlock, it happens up here," Moffat said, pointing to his head according to the LA Times. "Sex is brain work for him. Can you imagine romance with Sherlock? He'd poison his girlfriend just to see if it works." (RELATED: Who Is The Better Companion For Sherlock? Irene Adler Or Molly Hooper?)
10. PBS will be airing the new season with minimal lag in the US. Usually, the episodes air much later than when it airs in the UK. 11. There will be another season. "All I know at the moment is I'm doing these three [episodes of the upcoming series] and another three." What's more, "Sherlock" creator Steven Moffat told Radio Times that the two leads commissioned the next part of the series. "We had to inform the BBC that Martin and Benedict had commissioned a new series," said Moffat. "They signed themselves up. They both announced that they were carrying on -- so that's good. Benedict, at some red carpet event somewhere, said he was carrying on forever. Martin, at another one, said, 'Yep, series four is happening.'" "The BBC can do what they like," continued Moffat. "They're massively powerful, don't provoke them! But I assume that unless we've really screwed up Sherlock [series three] - which we haven't - it's a big success and it will carry on, so long as Benedict and Martin want to do it." 12. BBC will continue the series only with Cumberbatch and Freeman. Earlier this year, Moffat revealed that he would only carry on the show as long as Cumberbath and Freeman were interested, and he has no intention of recasting the roles and continuing with the series. "That show could not continue without Benedict and Martin. It's absolutely them," said Moffat at the Edinburgh Fringe Festival when speaking with DW Magazine. "Benedict and Martin have been announcing on various red carpets that they're happy to come back and keep doing it. It would be quite nice to do it for a long, long time - let them age and become the normal aged Sherlock Holmes and Dr Watson."
