The things I find.

one of the staff over at UbiWorkshop said they had some / several left over for if they mess up big again or feel the Ned to appologize to any customers
so they won't be sold or reproduced reprinted but they didn't print just enough for the Desmond hoodies
say there was 320 Desmond hoodie back log they would have ordered 40o prints
I known what you mean about the exclusivity but there wording is vague
as it says the print won't be reproduced but there are 3 ac3 books coming out that contain art so the image will probably turn up in one of them not as imprint but a image printed on a page

it wasn't solely for people who ordered the hoodie I have come across 2 people that had it for other heavily delayed orders but the delay was the same period of time so might have been a packing error that they got one
