I've always wondered if you and your team are mathematically taking into account that reported Xbox hardware revenue data includes revenue coming from sales of official Xbox accessoires, too, like headsets, controllers, storage expansions, etc.

And as far as that 21m+ shipment figure goes back in June 2023:

It could also very well be that they were simply displaying their projected total numbers up until their (fiscal) Q4 '23 already, since that presentation back then was only a few days away from Microsoft's Q4 being completed.

So it could be assumable that for THAT particular presentation back then, they themselves were rather eager to display the most freshest number up there than a number from March.

At least that's my personal opinion.

Companies can’t present projected sales data as official sales figures. That’s fraud.
