I think a large part of it is that demand for DSLR cameras and lenses is falling by the day. I'd wager you'd see much better prices if they were selling mirrorless gear. I think these companies know there's going to come a point where DSLR stuff just isn't going to sell anymore. Last time I was at Roberts Camera I was in their used camera warehouse and it's overflowing with DLSR camera and lenses. I think they just don't want any more of them.
Offensive DSLR pricing may just be another way to say to a seller NO, we don't want what you have for sale or trade,
DSLR parts are becoming difficult or near impossible to acquire, sadly it's a death knock into DSLR gear. In cases surpluses gear may be used for wrecking of parts and may well evolve for higher end DSLR products mainly.
We are even seeing a build up of mirrorless products emerging on the used market and in cases at low to reasonable prices.
The Z9 has been taking hits as well, some list prices on new mirrorless glass are softening from initial list retail prices.
I feel we will see many more dealers rationalise or even move away from any DSLR inventory.
For many people transitioning from DSLR to mirror les has or can be a financial challenge,
It's been no surprise,
DSLR to Mirrorless transition fundamentally is a major evolutionary change not just model upgrade.
The key driver is the world is largely moving to video, hence the industry hybrid stage or progression.
In contrast I even sold my Z9 recently and just took $5500 AUD or $3500 USD in a market of lots for sale used at around $6000 AUD or $3900 USD, I let it go slightly cheaper to a club friend to avoid the hassle of dealing with people I didn't know.
The major dealers offered to retail my Z9 (mint little use) for $6500 AUD less commission of 25% netting me $4875 AUD, Nikon recently cranked the Z8 Z9 prices to pave the way for high pricing of forthcoming models Z9 II Z7III etc.......undewr the excuse of increased costs and inflation, I mean really I think its still product positioning, only an opinion.
If you staying with DSLRs the benefit of falling DSLR prices is WOW what a bargain for some hi end good DSLR glass or gear.
Only an opinion
