I doubt it's gonna happen. As I've said before.
Unlike most of the other villagers introduced in DnMe+, Meow was only available as a promo villager tied to a specific e+ card given away somewhere (along with Bow, Nindori, Pierre, Shinabiru and Shoukichi) instead of being widely available in blind-bagged card packs like amiibo cards are today, so the people involved in distribution would have to essentially reissue these villagers as amiibo cards, which given two are literal competition entries (? I think? I seem to remember it being in the LGTTC Iwata Asks?) would be kind of impossible?
Nindori's got the best chance of returning, given he's Nintendo Dream's mascot, but even then I'm not getting my hopes up.
TL;DR this information isn't widely known (and the site that had the information on is currently down) but six villagers have very little chance of returning, please put this information out somewhere?
