I got this from WDW News Today:
Wasn’t That in October?
Yet another Epcot 25th anniversary pin will soon be for sale at Epcot:
This pin is scheduled to be released on March 13, 2008 at a retail price of $15.00 and is limited to only 500 pins. More anniversary pins are scheduled to be released before October 2008, when Epcot will turn 26 years old.
