Hello, I've been waiting for the korean course and just saw it was 95% done. Does anybody know approximately when it will be released? Thanks!
The Korean team estimate the course will be done in the middle of August (Aug 17, 2017). You can check their progress here: https://incubator.duolingo.com/courses/ko/en/status
Keep in mind the date can be changed at any time.
Hope this helps and have a good day!
Italian for Portuguese took about two months after the contributors locked the tree and handed it over to the folks in Pittsburgh (German for Italian, too). I think the August date reflects when the contributors hope to have their work done, which obviously can be pretty different from when the course actually goes into beta.
