It is not new that there is a new Fable that is being developed by a new division of the Playground Games studio, the studio responsible for Forza Horizon. A few weeks ago, an official Fable Twitter account had been sighted (which Microsoft had secured for a logical reason), but there had already been other indications, such as the Fable 4 listing in Mixer a few years ago.
As reported by the industry insider « Klobrille » from the ResetEra forums, the new Fable will be announced during the Xbox Game Showcase presentation on July 23. According to this insider, an in-engine trailer (that is, created with the game’s graphic engine) will be shown, similar to that of Hellblade II, not gameplay, but Shinobi602, another renowned insider, claims that there will be gameplay. We will have to wait to see which one will be shown (perhaps it is a mix of both), but there is no doubt that it will be announced.
But speaking of gameplay, Microsoft announced, a few days ago, that it will finally reveal gameplay of the expected spiritual reboot of the Halo saga, which will launch for PC, Xbox One and the new Xbox Series X console in late 2020.
