The 4080 was priced poorly to push people to old RTX 3000 stock. The high-end RTX 3000 stock is largely depleted now (Newegg is showing the RTX 3060 Ti as the highest-end RTX 30 card in stock), so I would expect Nvidia to make a price adjustment to realign their products, especially with the 7900 XT/X just around the corner.
This does not apply to the RTX 4090, though. It's a halo card, and as such, the price can be inflated compared to other lower GPUs and it will still sell.
