It appears that a new 'Character Meet and Greet' location may be coming to Epcot. Disney recently filed a construction permit, described as 'Epcot - Front of Park meet and greet'.
The most obvious place for this new location would be in the former pet kennel building which is currently empty. It could however be a smaller area at the entrance where there is currently an outdoor meet and greet area.
Disney have yet to confirm this new addition.
