Calling all Sherlockians!
Season 4 has officially been scheduled. And while it's going to be a while before the actors' schedules can be coordinated (thanks Marvel), we do know that Moffat is planning on a 2017 release. So... that's only a three year hiatus! And we JUST had the 2015 Christmas special. So really, that's barely any time at all.
WE CAN MAKE IT YOU GUYS
But so we don't completely lose it while we wait, what are you hoping to see in season four? I'm sure everyone has lots of ideas! Hopefully you can keep everyone occupied until 2017...
