The release window for the Xbox Series X has finally been revealed by Microsoft as the Holiday of 2020, giving us a 3 month window, October to December.
In previous years the Xbox has released in November so we would expect them to continue with this as a staple release schedule.
Despite many concerns over hardware releases due to the Coronavirus, it is unlikely Microsoft will delay, as we know the PS5 is due for release this year, and Xbox would not want to miss the initial release as they did with the Xbox One.
Xbox has been a proud partner to many online conferences, so it is likely that if we do not have a physical conference then there will be an online version.
