Pretty sure they meant Xbox One/ Xbox Series. The even mention wanting to drop Xbox One ver.
Notice that nobody is complaining about Series S yet. In this case, it isn't even a concern, while XOneS is. It seems to me like Series S can do the same features as Series X, but at a lower resolution, just as some have expected. Also, it might even be able to do DLSS style machine learning upscale, making it look very close in appearance to native 4K on Series X. We'll have to see what they announce.
People on here have deluded themselves to think the X1 isn't a hinderence to next gen game development.
The series S will be fine. Same architecture, same features, same dev tools, has all the velocity stuff, same SSD. Nothing there to hinderence game development.
