Once that happens and essentially 25% of the buyers market goes away, I would be surprised if prices didn't go back down.
I keep seeing people saying this and while it would make sense at first glance do remember that Nvidia is very much aware that a big chunk of their market will be gone soon, and they've known for a while (way before us randos learned about it). If Nvidia appropriately managed their production in anticipation of this they can keep prices higher for a while. Not forever, but at least until early next year. You can also be sure they won't let the prices do down even a dollar below MSRP until the Super series is out. Can't have a "cheap" 4090 make their 4080 Super look worse.
Because look how well it works, this is once again an Apple hatebait thread that tops /r/hardware , as is tradition.
