Right. But, there were also 2 TB variants of the Xbox One S (not sure about the PS4 or PS4 Pro). But to the best of my knowledge, no 2 TB variants of the Xbox One X. So the Xbox One consoles went as high as 2 TB, only to eventually settle back down to 1 TB HDDs as the one and only option for all variants.
I think the important point was that they experimented with larger-than-1-TB and, for whatever reason, appear to have decided it wasn't enough of a selling point. At least, last-gen it wasn't. You could argue that it's more beneficial for current-gen console, and yet it costs more at the manufacturing level to add more storage to current-gen consoles (which argues against them wanting to do it, at least for now when they're A) selling every unit they make, and B) trying to keep costs down).
Of the four variants of current-gen consoles, all indications are that the Series S will be the first to become generally in-stock/available. The Series S isn't currently generally available in stock everywhere in North America, and may not remain so elsewhere as we get closer to the holidays, but it's nonetheless on the earliest trajectory to being so. Which likely means the earliest price cut, or value add (such as a bundle) will likely come to Series S. And it also means that the earliest upgrade (more storage, or whatever that upgrade is) will likely also come to Series S.
Microsoft seems committed to the Series S for the long-term (they have predicted it will ultimately outsell the Series X), but they may recognize that the current Series S might be perfect for India, Brazil, etc. Whereas we get a new Series S with more storage, or an optical drive, or whatever upgrade they deem it needs to be more successful in North America/Europe/Japan/etc. In that scenario, we'd likely get both options in developed markets, I suspect.
