Disney would never release anything that is not family-friendly (e.g., appropriate for children) under the Disney label. In the past, they would release such content under a different label, such as Miramax (no longer owned by Disney) or Touchstone Pictures (now defunct). Going forward, they will probably release them under 20th Century Studios or Searchlight Pictures.
If this is true, that's great news! But, as others have mentioned, it sounds like this could be an international project presumably in English, and subsequently dubbed in other languages.
Disney is primarily motivated by profit and not willing to take risks, so they will not invest in anything unless there is a guaranteed financial return.
