So I called Sideshow about this earlier and got some interesting answers about this.
They charged for Ahsoka because they got notification that the ship the Ahsoka (and other Hot Toys figures) were on reached port and is docking. They started charging to expedite the shipping as soon as she's in the warehouse. I asked if charging before Hot Toys putting the final product photos up would be normal in the future and they said the dual release is at the request of Hot Toys and they think Hot Toys wants to do dual releases like this on figures that are delayed moving forward but we'll see.
Just passing along what I was told.
