The Famitsu data includes several days before the unwelcome announcement. Even so, buyers are already shying away from PlayStation consoles that are straining wallets . The PS5 with optical drive moved 558 units, down from 2,801 sold the week before. Not faring any better, adoption of the Pro went from 4,662 to 840.
Whilst it’s an oversimplification, if the old price only got Y sales then a higher new price was always only going to get a subset of Y.
Console sales go up over time in part because the price goes down, broadening the customer base. Sure, the library gets bigger over time too, but that’s barely happening either.
Plus people knew the increase was coming so I imagine there was a spike in sales just before hand.
