Some problems with your assumptions here:
# 1 There are definitely some PS5 exclusives that aren’t available on PS4.
# 4k as the PS5’s sole purpose is obviously also very shortsighted. There are several PS4 games that run at 900p and / or 30fps or lower. Also in terms of image quality, you had to make choices on a PS4, which you don’t have to do on a PS5 (if you actually do it is a completely different story).
# 3 The PS4 is now 9 years old, and as it turns out, games are still coming out for that … Isn’t the PS5 likely to get 9 years of gaming too? Of course it still looks like coffee grounds, but on the one hand we discuss a 7 year cycle and then mention games that are made outside those 7 years for the same console …
I don’t have a Playstation and I don’t even expect to buy one (at most PS streaming with subscription). So it is of little use to argue too much “for” the PS5, but … The PS4 produced 106 million units in 6 years. The PS5 now 25 million in 2 years. But that’s with limited supply and even more demand than supply. They have now doubled production in the last quarter and can produce another 100 million units at this production rate over the next 4 years (for a total of 150 million units over 6 years). The question, of course, is: is there so much demand now and so much demand over the next four years? You say no, but 25 million people are significantly more than “everyone” in your statement …
There is a possibility that more people will leave for the console from the PC. Huge prices for new high-end and “mid-range” video cards and CPUs are already a problem in these troubled times, plus extremely high power consumption, which is no cheap joke in this energy crisis. ..
