Xbox Director of Program Management Jason Ronald has made clear that there are unannounced Xbox games scheduled for release in 2021|
Speaking on an Iron Lords Podcast episode about the Xbox Series X and S, Ronald was asked what game he was most looking forward to in the year ahead, to which he replied, "Not all games that are releasing this year have been announced."
While not specifically referencing Xbox Games Studios games, the remark has sparked speculation about whether Ronald is referring to games coming from Microsoft's owned studios – or even its soon-to-be owned studios, given its acquisition of Bethesda has taken major steps forward over the weekend. Ronald didn't elaborate on the point.
The 2021 Xbox lineup already has heavy hitters like Halo Infinite and Psychonauts 2 on the way but, clearly, Microsoft is planning to add more to the roster. Interestingly enough, Xbox Marketing boss Aaron Greenberg recently said at the start of the month that there was "nothing coming soon" with regards to major game announcement events, so perhaps don't expect these mystery games to be revealed in the extremely near future.
