Groundspeak will not retrospectively award Mega Status, and have stated that it is very unlikely in the future, will Mega Status be awarded until a Event has already crossed the 500 person threshold in the first year, so will be awarded Mega status for following years.
Events connected to a Mega/Giga will not be awarded Mega or Giga status, as they fail to stand on their own merits for such status, as people have been attracted to attend by the Mega/Giga that they support.
Because of it's unique Icon, the GPS Mae, can not receive Mega/Giga status. But both a Mega/Giga are allowed to take place in the same time period, and close proximity to a GPS Maze. where other events may not take place at the same time and in the same general area as a Mega/Giga event.
