"According to our sources, there are two consoles currently being prepped, aiming for a 2020 holiday debut — a cheaper "S"-style console, to succeed the Xbox One S, and a more beastly "X"-style console, to succeed the Xbox One X. The codename for the "S 2" seems to be "Lockhart," and the codename for the "X 2" seems to be "Anaconda," which may also be serving as a dev kit."
"We've been reporting on Microsoft's efforts surrounding Windows Core OSfor a while now, and it does appear that there's a gaming angle to the puzzle. We've heard from multiple places that the next-gen Xbox consoles will be fully compatible with everything on your current Xbox One consoles, including your OG Xbox and Xbox 360 library via backward compatibility. We've also heard that Microsoft is working on a new delivery method for games dubbed "Game Core," as part of Windows Core OS, which the Scarlett family will support when it's ready. It extends the work Redmond has been doing on UWP.
Game Core should make it easier for developers to build games that function not only on Xbox "Scarlett" consoles but also Windows 10 PCs, further reducing the amount of work studios need to do to get games running across both platforms. We'll hopefully hear more about Game Core either at GDC in early 2019, or a bit later at Microsoft's Build conference"
"We've heard that Microsoft has been working with accessory vendors like Razer and others to ensure that Xbox gaming on mobile is as streamlined an experience as possible, with a range of new accessories, and maybe even devices, that will take advantage of the mobile possibilities that Project xCloud will bring."
