Martin Freeman, Benedict Cumberbatch, and Steven Moffat each won an Emmy for their roles in Sherlock Monday night, more importanty, Steven Moffat and Mark Gatiss have revealed some juicy new tidbits about the new season's story. 

E News reports that Moffat, when Speaking about topping season 3, said, "We have a plan to top it. And I do think our plan is devastating,' he replied.

'We've practically reduced our cast to tears telling them the plan ... we're probably more excited that we've ever been about Sherlock.'

At the HBO after-party, fellow Sherlock writer-producer and actor Mark Gatiss teased a little more about season 4: "We're going to try to take it somewhere we've never been before - and I don't mean outer space," he said. "It will be challenging place to go. We always start with a re-introduction that builds toward a darker climax - we might just be going darker [from the outset]. We got a very, very good set of ideas."

Backstage, Moffat also revealed "I didn't think we'd win anything," he said. "I'm a bit worried about rewinding and seeing my speech ... we were just starting to think that phase [of getting awards attention] was dying down ... hopefully more people will watch it."

As previously reported, Seaosn 4 will be coming in 2016, and the BBC has greenlit a Christmas special to come before that.

Shooting for the show is postponed due to the Benedict Cumberbatch and Martin Freeman's availability.

Producer Sue Vertue told Radio Times that they are working on the dates already.

"We're working on it. We're working on dates," she said.  Co-producer Steven Moffat added: "We'll get them made as quickly as we can."

Co-creator and co-show runner Mark Gatiss confirmed this as well, saying "[We] moved significantly closer to getting a date in the diary for series four."

So lets do some creative/ speculative back tracking. Benedict Cumberbatch has already teased that Moriarty is coming back in some form or another. We also know that they stick somewhat to the books, in which Mary Morestan dies. So, best guess, would be the devestating plan Moffat is talking about involves Moriarty killing Mary Morestan. To take it a step further, it is not impossible to envision a scenario where Moriarty forces Sherlock to choose between Mary and John Watson, which will make Watson resent Sherlock. Of course this is all speculation, but it makes sense within the confines of the show.
