Is Pirates of the Caribbean 5 going to be released to theaters in 2014 or in 2015?

My guess is 2013 and 2014. After the first part the team waited for 3 years and released the 2nd and the 3rd part in 2 consecutive years respectively. 4th part was released after 3 years. hence I feel we won't have to wait long for the 5th part.
