I think soon enough we're going to refer to it all as the Xbox platform in vague descriptions like this.
It will just be "Xbox" going forward, after a year or two of becoming accustomed to it. In technical breakdowns (like comparison videos and so on), we still compare Xbox Series S vs. X (And if they introduce a new 'series' in the future), but I think we'll think of the platform similar to how we think about PC software. Like, a game gets released on PC and there's dozens of iterations below that, but the general platform is PC -- WIndows based x86 platforms.
I have noticed some funny plural vs. singular differences. Like, Playground Games had a tweet yesterday that said "Starting NOvember 10 the best console to experience the Horizon Festival is Xbox Series X and Xbox Series S" or something like that. It was using the word "console" in singular, but then mentioning two distinct boxes. So I think that's the direction they're going, but over time we're going to get used to just calling it "Xbox"
I think their intention is to mimic something like how BMW models their car lineup, and even as a non-car head I still know what they mean by it. Like, the BMW 3 series, 5 series, and 7 series are the most common ones in north america (that I know of at least as a casual person). THe 3 is their smaller, sportier looking, not crazy engine or anything. The 5 is the midsized one, more power, more room. The 7 is the luxurious land boat, lots of power, luxury focused. (I could have these wrong, I'm sure a gear head is losing his lunch over how I'm wrong with them). And within those series, you have different versions... like the BMW 3-series sedan vs. wagon, or the 3-series w/ the "M" which indicates the most powerful or fastest one in the 3 series. Casually someone might say, "oh yeah I rented a BMW 3 series..." or "Wow, the rental company gave me a BMW 7 series because they were out of Mercedes C-class..." or something. Which reminds me that Mercedes does something similar... Mercedes C class, E class, etc.
