IMO Welfare is an..."interesting" character. He is extremely bullish on Xbox sales numbers, to the point of almost being a parody at times. One minute he can be blunt about it selling at OG Xbox levels, the next he is putting out numbers that would make VG Chartz blush. It can get ridiculous at times.
We do have the estimate of 20.5 million X/S systems Ampere provided as of EOY 2022, earlier this year. I think I've seen others, maybe it was even you (?), estimate ~ 1.3 million - 1.4 million X/S system were sold from January to March this year globally. If we're bullish and assume the Ampere numbers were sold-through (I think they were sold-in; if they were sold-through, surely MS would have noted that in their quarterly fiscal results to boost up reported number optics since that would have had them ahead of XBO still), then that'd of been at least 21.8 million by end of March. Maybe 21.9 million.
23.9 million, even if representing shipped, would mean another 2 million between then and end of June, and probably at least a good portion of them just sitting around in channels. But, that would probably have already been happening months ago. I'd also suspect the new Series S is to rejuvenate sales of the lower-end model while maximizing their wafer production allocations (probably still on 7nm) and make up for slagging sales the past six-plus months. Because they can't realistically "only" increase Series X production volumes without incurring a lot of wasted money since so much of their wafer allocation would be going unused.
With that all said, your 23.2 million shipped is probably the more realistic estimate of the two. What the sold-through is? At this point I would have no idea, but it'd certainly be below 23 million.
They're too scared to do it.
