The season three finale of Sherlock left fans with many questions. Not only did Sherlock get called back to London after being exiled for 4 minutes. But Moriarty, Sherlock's greatest foe is back and ready to cause Sherlock more turmoil.
The creator Steve Moffat has confirmed that there are plans for [Sherlock](series:201416) to not only have a 4th but 5th season.
With the first 3 seasons having a two year spacing between them many fans are hoping for the next season to come more quickly.
Although this may be hard to achieve. Martin Freeman, John Watson, has upcoming filming for his next movie in [The Hobbit: The Battle of the Five Armies](movie:512312) where he plays Bilbo Baggins of the Shire. Benedict Cumberbatch, Sherlock, has some upcoming filming as well.
According to the creator, Moffat, due to the actors conflicting schedules it could take a year to a year and a half till they can start filming the fourth season. This will keep the fans guessing about Moriarty's return for a while.
But what do you think? Will we see Sherlock make a comeback, or will their other duties keep this from happening? Write in with your thoughts below the line!
