Just because Canon prices the R6 at USD$2500, I don't buy the argument that an APS-C body with similar features must naturally be priced there as well.
There is no precedent in the current market for a $2500 USD APS-C body. The most expensive APS-C body I am aware of is the Fujifilm X-Pro3 ($1800, without the dura finish), but I think the $1700 X-T4 is a better option for 7Dii sports/action/wildlife shooters looking to move to mirrorless, that or the $1400 Sony a6600 (prices in USD at B&H as of this date).
All three of these bodies check the boxes for the standard high-end features: Magnesium alloy construction, weather/dust resistance, fast AF, face/eye AF, animal eye AF (Sony, not sure about Fuji), IBIS, 200K (Sony) or 300K (Fuji) shutter rating, 4K video (no time limit on Sony, not sure about Fuji), and a large image buffer. The two Fuji's also have dual SD card slots.
If Canon does make an "R7" with similar specs, they very likely will price it well north of $2K. That's their prerogative, and I'm sure there will be many compelling reasons why people will be willing to pay that much. I'm not judging, in fact I might even be one of them. But that price and that feature set do not inherently have to go hand in hand with one another.
