There has been a world wide chip shortage, try to get a GPU in the last couple of years? Heck automotive manufactures weren’t able to get chips. Never mind there are supply chain shortages for a massive range of products outside of chips. This is not a unique to current gen console issue.
PS5’s aren’t hard to get now either. I removed my in-stock notification on twitter because I was being spammed with restocks and I already have mine.
