Well we keep hearing this is on and off again and I just got this from a trusted source from a recent EE order,
"Thank you for ordering from Entertainment Earth. We have been notified by the manufacturer that we will not be receiving any additional shipments of Star Wars AT-AT Driver Classics Bust, (Item GE10596), because they have discontinued production of this item at this point in time. The order you
placed for this item has been cancelled in our system."
I have this on pre-order from Gentle Giant themselves and will go look to see if they are cancelling thier orders. This line seems to be dead correct? Who knows?
