Nintendo are very busy but if it was really submitted a month ago then it shouldn't be too long. It's not like Steam where you can just upload a patch and click live, Nintendo need to review it.
We had a 5 person group all buy it around the same time and that's all we talked about "lol at the abusive mom always at the pub hearts 4 beer yo". But 2/3 through year 2 it cookie clickered it up.
