Raspberry Pi rolled out its 3GB Raspberry Pi 4 for $83.75 and raised prices due to increased memory prices. The company outlined new prices increases for a series of systems. That news isn't all that surprising, but this tidbit is: Raspberry Pi said it will reverse the increases once memory prices ease.
"We’ve said a number of times now that memory prices won’t remain at their current very high level indefinitely; the circumstances in which we find ourselves are challenging, but in the future they will abate. When they do, we will reverse our price increases, and until they do, we will continue to work hard to limit their impact in every way we can."
You may hear something similar from other hardware vendors, but I kinda doubt it.
