Not so long ago, one of the project managers for Xbox, Ben Decker, gave an interview to GamesRadar, in which he said that the new project from Microsoft "will blow your mind". He mentioned this when he said that gaming companies are working on several new games at once, including Halo, Forza, Fallout and a new, unnamed project.
Decker said that at the moment Microsoft has 23 studios at its disposal, which are working both on already known releases - and on a new project that will amaze the players. He did not mention anything more, but noted that the new game could appear in the Xbox game library immediately on the day of release.
Interestingly, the 23 studios Decker talked about are independent developers working for Microsoft today, which means the game could be from one of those studios. Alas, we can only guess what this game will be about. It is quite possible that this is a new project of the Danish studio IO Interactive, which gave us the Hitman series of games. Recall that the studio's last game was Hitman 3, which was released in early 2021. In April, it became known that the IO Interactive team was working on a game tentatively titled Project Dragon, a fantasy RPG about dragons. It is possible that Decker was referring to this particular project.
Anyway, we can find out more details this summer, during the joint presentation of Xbox and Bethesda. Recall that Microsoft is still silent, whether this presentation will be part of the big gaming exhibition E3 2021 - or we will have a separate meeting between Xbox and Bethesda with the players. E3 will take place in early June, so there isn't much time left for Microsoft to think.
As a reminder, the Xbox turns 20 this year - in honor of this, the company is planning an anniversary release of Halo, as well as special merchandise.
