Update: Fortnite for Switch has now been found listed on the Korean Ratings Board website (as spotted by Twitter user Nibel), lending more credence to the earlier leak.
The application for rating was apparently provided last week, and approved today.
Original story: According to an alleged leaked E3 document, Fortnite may be coming to the Nintendo Switch.
The leak originated from 4Chan, with a supposed document indicating Fortnite as one of several unannounced Switch titles allegedly being revealed at E3. Corroborating the photo, sources speaking anonymously to Kotaku said Fortnite would be coming to Switch.
