"It’s still in development. Drew Pearce is working on the script and Downey, as you know, is still finishing Iron Man 3 so we’re waiting for Downey to finish that movie and to get a script from Drew. It is a high priority for the studio and all for the filmmakers involved… We want to make the right movie. We got a great response to the second movie and frankly the Moriarty character sets such a high bar that we want to make sure we’re telling the right story for the third movie."
And then he was asked about the different locations that could feature in the threequel,
"I don’t want to go into details about [characters returning], I just want to say that there will be some new locations, new settings for the third movie. Just like Sherlock for the second movie took us in a new location; the third movie will take us to a new location as well."









Even before the release of the first "Sherlock Holmes" film, there was already talk of a sequel, but when it was released, the talk of a sequel died down and now it's basic rumors that are left for the sequel. But now the star of the movie, Robert "Iron Man" Downey Jr, officially confirmed that he's back for the role and that he will be back in London this Autumn, where filming will start on the highly-anicipated sequel to the 2009 Guy Richie box-office smash hit. Downey Hr confirmed this whilst being interviewed by Jonathan Ross on friday night on his chat show, but Downey Jr was being interviewed via satalite in LA.
