A recent rumor suggests that Microsoft is considering a new Xbox One SKU that removes the disc drive as a cost-reducing measure.
As reported by Thurrott, this console would very much be part of the Xbox One family of devices and not the next-generation group of hardware that could compose Scarlett. This rumored Xbox One is expected to be released sometime in 2019, possibly as early as spring, and sell for $200 or less. The rumor also maintains that any Scarlet consoles would end up coming later, sometime in 2020.
