Technically “next Sunday” is the nearest Sunday (eg “sunday of next week”), however next Saturday is not (because it’s the Saturday of next week"). This assumes we all accept that Sunday is considered the start of the week - which isn’t always the case nowadays.
It’s chaos! But I’m just pointing out that there’s a wired logic to it, which I assume at some point made more sense than it does in our time.
That article is from Jan 2023 when Sony responded to a Bloomberg report that they had cut production due to lower than expected launch sales.
It’s possible they will rebut this article too, but they haven’t so far AFAIK.
