A friend of mine who works for Disney (not a standard cast member I have been on here long enough to know when info is crap) told me that a 6 month pirates refurb is being planned to go with a possible reopening in time for the holiday season of 2015. The only reason I am posting this is because this matches up with what I believe @TheGhostWithTheMost said about the imagineers wanting 12-18 and phil holmes saying 6 at most.
