This will be released in Thailand on September 15th, if Google Translate and its posters are to be trusted. It will be out in Japan on October 22nd.
No news of its South Korean release date yet, which is strange considering this is filmed in Busan and has Korean actors in every segment. Famous actors too. I can't find anything on it on the Sidus FNH (company in Korea) website so no clue.
Anyway, hope we get a release date or DVD at least. SOON! Here's a new still from Kang Dong Won's DC gallery.
