According to this Allspark article, Unicron.com will be selling their "Iacon One" sets at Botcon.
Now they don't refer to Iacon One but of course, it is exactly the same thing. It may just be shrink-wrapped in a baggie and not in the "cylinder package", but this actually kind of miffed me.
Sure they probably need to make money off this but this was something unique and special for the Iacon One show.
To just resell them at Botcon kind of makes having them at Iacon One totally pointless.
