Pues sí, eso parece aunque no parece confirmado.
Tomorrow will be the last day for Oddworld: New 'n' Tasty, Resident Evil, Sky Force Anniversary, World of Van Helsing: Deathtrap, and Mega Man 9 to be played on Xbox Game Pass. They will be replaced by five new titles by November 6th, with more due to join the program on November 10th during Microsoft's XO18 event. However, there's one more title now due to leave the service soon: Fallout 4.
We're not sure for certain, but current indications are that the game is due to leave the service on November 13th, especially as Microsoft tends to give notice of two weeks for games leaving the service.
