Right now, Xbox only has the Series X lined up for the next generation of consoles. But rumors have spread around of a second model, code-named Lockhart, and more evidence of its existence has surfaced today.
Security researcher "TitleOS" on Twitter posted some excerpts from the June 2020 release notes for the Microsoft Game Development Kit. In the notes, it specifies profiling modes for two models under the Scarlett dev kit: Anaconda and Lockhart.
The Xbox Series X is so far all that Microsoft has announced, though rumors of the Lockhart model have circled since 2018. According to a report from last year, the second model would reportedly be slightly less powerful and also not have a disc drive, offering a theoretically slimmer and cheaper offering alongside this holiday's Xbox Series X.
Sony has already revealed both versions of its next-gen console, the PlayStation 5, one of which is a discless Digital Edition. There's been no reason to expect that Sony's digital-focused PS5 would be any less powerful than the disc drive version, though; so far, the difference seems to be more cosmetic.
Though we've seen a fair number of details about the Xbox Series X hardware, there's still time between now and the holiday season for Microsoft to confirm a second version of the Xbox. If that ends up being the Xbox One S to the Series X's Xbox One X, it could present an interesting offering to compete with Sony's next-gen plans. The next Xbox event on the docket is in July and reportedly centered on its first-party game offerings, but we'll see if any more news comes of it.
