Nah, like any other console in gaming history, after having passed its hardware sales peak year (last year for PS5) it declines. PS5 is performing almost like the PS4 even if PS5 had the shortages issues and couldn't price cut the console as PS4 already did at this point, but instead had to increase its price.Latest YoY quarterly console sales are showing a very sharp decline that we didn't see in the PS4 era.
Traditionally, at the 4 year mark the consoles would have been much cheaper than they were at release, bringing in a second wave of buyers.
The PS5 is apparently not getting that second wave, ever.
In fact, PS5 is outselling PS4 launch aligned in several of the top countries, it's some EU countries where PS5 is performing worse than PS4 launch aligned, which makes PS5 to be launch aligned abit behind PS4 worldwide.
Launch aligned PS5 is one of the most successful consoles ever in gaming history even in sales units, its weakest metric:
(in most of the other key metrics PS5 is the best performing ever)
Regarding the peak year, as can be seen in the graph it normally ranges somewhere between the 2nd and 5th fiscal year depending on the console (this graph covers until the end of each FY, so it's updated until March 2024, since PS5 had the peak last year the following quarters until it gets discontinued should be normally declining YoY, as happened almost always for all consoles in gaming history.
