Microsoft's mid-generation plans for the Xbox Series S and X consoles looked a whole lot different a couple of years ago than it does now. A leaked slide deck from the FTC v. Microsoft case last year outlined detailed plans for a spruced up Series S, an overhauled Series X, and even a redesigned controller. Another part of that roadmap included a streaming-only version of the Xbox, codenamed Keystone, that was designed to connect to Microsoft's Xbox Cloud Gaming servers rather than rendering games locally.

Microsoft has talked openly about this version of the Xbox before. Microsoft Gaming CEO Phil Spencer told The Verge that the Keystone console was designed and fully functional, but that it wasn't launched because Microsoft had a hard time getting the price down low enough that it made sense next to the $299 Series S (which already occasionally goes on sale in the $200 to $250 range).
