The first trailer for Fable IV appeared two years ago. Unfortunately, there is too much speculation on the Internet about the release date or any other details.It will be interesting if at least this year Microsoft and Bethesda share some new images, game play information or game engine.
Fable IV will probably use the ForzaTech engine seen in Forza Horizon 5. Again with the rumors in 2018, Don Williamson, the former chief programmer of Lionhead, tweeted that he knew about a studio working on Fable IV, although he has since deleted his post. This studio seems to be Playground Games.
