I don't want to get your hopes up. I didn't find out about Hollow Knight untill after all the dlc came out. I haven't been waiting that long, just a couple years, so I'm probably not as jaded as the rest of the community.
It looks like that it will come out by the end of the year. I forgot what I read exactly, but some paperwork getting processed. Of course I will gladly put on my clown make-up when December comes and goes with no word from Team Cherry. 🤡
