Just anecdotally I think this has been the case every time a new WiFi standard is commercially available. WiFi 6 TP-Link AX1800 WiFi 6 right now is $80 unless one wants the 2.5Gb ethernet ports and that one is $230. I want to say that one was about $500 not that long ago. When WiFi 8 is commercially available I would expect 7 to be the same as 6 is right now.
Just me personally, I avoid anything that new. There are usually serious bug and compatibility issues in my limited experience. Unless one has a special need for 7 I think right now 6 would be a safer move in my opinion. I see several different WiFi 6 brands that range from $50 to $90.
It can also support 16 MIMO or 4 x 4 MIMO with 16 Tx & 16 Rx or a total of 32 antenna.

Do people regularly upgrade home routers? I typically just buy a new one when the old one dies.
If not, a two-pack of “Eero 6+” is $154.99. That’s a very good price IMHO. And one needs a quite large home in order to need a three-pack, so I think the two-pack is sufficient for most households.
