Only just found out about the Megatron being a convention exclusive toy. A little bit annoyed that they are again having Megatron left out of the set, to be one of the 'at con' toys. I can understand that a five pack can only have a certain total size of figures, but they should have had Megatron in the pack instead of Optimus. It would have balanced up the Autobots and Decepticons a bit more as well.
