I doubt AMD would be making these X3D units in any appreciable volume, that it'd need to drop prices down the road. There is no competitive pressure to markdown the X3D, as Intel doesn't have an equivalent. The only reason to drop pricing is to move inventory, and if there's no inventory to speak of, then no markdown.
The 5800X3D largely maintained its MSRP from release (April '22) to Black Friday, only dropping a small percentage in the months before,
This was after the 7000X release, with the life-cycle of the 5000 series coming to an end. Extrapolating this to the 7000X3D, EOL won't happen until the 8000 series comes out, which is probably at least a year away.
In short, if you're waiting on the X3D to drop price before buying, don't.
The X3D's high pricing is understandable, as its main goal isn't to sell in large volume. As with Intel's KS chip, the X3D line is intended as a halo product, to allow AMD to claim the "best gaming CPU" throne, thereby boosting the Ryzen brand. It's intended to win benchmarks and bragging rights.
The X3D's intended audience are deep-pocketed gamers who are willing to pay for "best-everything," as games are GPU-bound for the vast majority of cases, and "best gaming CPU" is rarely needed. This demo isn't price-sensitive, so pricing these lower would be leaving money on the table. "Value" gamers need not apply.
