If I had to guess, I would say that the EB employee did not necessarily know what he or she was talking about.
In my experiences (and as a former retail employee myself) retail employees generally have NO idea what items will be coming in, or when. And if the person that you spoke with was informed, they most likey meant that the figures had not left the EB Warehouse... They would have no idea about the factory.
I am 100% certain that Ken has not misled us about the fact that the items have shipped. Why would he do that? In the retail world it takes a long time for things to go from the factory, to the retailer's warehouse, and finally to the individual stores.
Be patient! I am sure they will be all over the place soon enough!
