In some regions this came out in early 2017. In a limited number of others it came out in the middle of the year. In my region, it just hit store shelves and was actually the first set of the season for me to come up with a "DO NOT sell until" embargo at the checkout register, listing a street date of Dec. 1, 2017. A manager was kind enough to do an override... for this months-old... $4 set.

It's funny to see the diametrical shift in comments between two back-to-back videos, from "It is impossible for you to have this set because it does not yet even exist on the planet" to "This is set is so old it makes absolutely no sense for you to review it [sic]" in minutes!
