I havent even touched the wedding event at all so the last time i "felt" there was an update was longer than that. I say it is no way they are going to abandon it, it brought so many new players to the franchise and i know of several people who never played an animal crossing game before but were excited to get nh because it had crazy hype around it. Gotta admit that i didnt start actively playing games with this kind of model until recently so i have no idea about what could normally be considered as a long "waiting period" between updates.
