The release date for Respawn Entertainment's Star Wars Jedi: Fallen Order, the singleplayer Star Wars game that will be revealed in full later today, appears to have been leaked, with a launch date apparently set for November 15. 

The date was mentioned yesterday in a Reddit post showing two Star Wars pin badges, although user timochappy23 did not post a picture of the back of the pins, where the date was supposedly written. However, Twitter user Nibel later posted an image of the back of another badge, with the line "Available 11.15.19" displayed. You can see the tweet below.
