Yep, although they were on the map as 'coming soon' for at least two or three years beforehand, the whole thing took ages. My best guess is 2021 but I'll root out my own maps from visits and see if I can make sense of it.
I have a couple of maps from Pafos Zoo, both acquired from zoo nerds living in Europe via trades. My guess was 2020 for the date, as the "coming soon" words seem to have been on the zoo's various maps for years.
