I recall during the PS3 and PS4 days, console bundles sold out within days; especially at retail stores; after their initial release. Yet, I still see God of War and other bundles available at retail stores & online... years later after their initial release window. That should raise questions about Sony's claims regarding how well their current system is selling compared to previous generations.
Sony is running Black Friday deals for PS5 shoppers with $100 discount on all consoles, as well as some bundles. The PS5 Pro is also discounted this time around.
