That's crazy

With such prices, buy yourself a weekend trip over France or Germany, and buy a better PC over here. And it would still be cheaper.
Basic example in France (a store that is far from the cheapest and has physical stores - including Calais right outside of Eurotunnel)

Seems better, and once converted is over 500£ cheaper. Leaves room to add yourself some more RAM and bigger SSD, plus extra to save.
Numbers are still very good. But even with new version, it started decreasing in 2022.
But you're right, the main incentive is coming for developers. It really is outdated, and most AAA devs wants to get in but cant. (and need cloud)
Also, Nindendo has history to massively fail every generation after they succeeded :
NES/SNES = 110M -> 33M N64 -> 22M GameCube
Wii 100M -> WiiU 13M
Switch 146M -> Next ?
Handheld consoles are different ... and I guess that's also part of the success of Switch, and why they will continue on this path.
(and I already know there's too much numbers !)
