Actually my argument is that Xbox problem with the lack of sales is the lack of demand, not the lack of supply. Your colleagues seems to think that Xbox is supply constraint when the cheaper model is widely available everywhere. There might be a slight supply problem with the model X, but I doubt it would make a significant difference in sales. The problem with Xbox outside of UK and US is the lack of desirability and demand for the product, not the supply. And even in those countries where Xbox has "strong" sales, they still ended up dead last. Sorry if the facts hurt your feelings.
Oh and it doesn't take much effort to incur some growth after the failed Xbox one product. I mean, it was a disaster anyways. A better comparison should be the growth from Xbox 360 . How does the Xbox series compare to Xbox 360 is a much more fruitful comparison IMO.
Its like saying the Switch is a runaway success compared to the WII U.
If the Series X is constantly selling out, it stands to reason that there’s demand. A very real demand.
And yes, wider supply for the Series X would make a significant impact on sales. We’ve seen that happen already this year, where improved stock of the Series X led to sales spikes for Q1 2022.
It’s also common practice for growth to be measured against your last outing or a previous predetermined period. It makes no sense to compare vs the Xbox 360, or for you to compare the performance of the Switch to the Nintendo DS.
I do empathize with your situation. As a kid, I used to try to diminish the sales of Sega’s Genesis when I could only afford a SNES. If you could just devote your time to raising $499, you probably wouldn’t have to do this. Couldn’t you ask your folks to up your allowance?
