Xbox One X is really Xbox 3.5.
So no, the next Xbox cannot be Xbox 5.
Xbox One V. As in IV Roman numeral for 4, but still has a 5 at the end.
The official name could be just xbox but you need something there to distinguish between models.I will be shocked if it isn't simply Xbox going ahead as it lends itself well to their catch-all services and platform.
I kinda like this actually.I still like my suggested name from awhile back, Xbox 365. A callback to their most successful era, that emphasizes the systems ecosystem and xcloud/game streaming always available, and still manages to put a 5 in the name of the system
