I'm thinking something closer to the latter option. The said seller has a number of WDI pins for sale, which I don't believe have been scrapped.
Heck, even if it was a scrapper I'd get it. It's gorgeous.
EDIT: After some digging I've pretty much confirmed that they are a Disney employee. At least as of 2015. I won't say any more details - but I don't believe the series has been scrapped.
Double edit: If this is part of series 2, and not a later series, than our theories about chronological releases have been thrown out the window... I wonder if this is actually for a later series.
