I was able to score one of the 20th Anniversary Editions on release day. Let's see if my luck still holds up for this one. However, it did take about 45 minutes of mashing refresh in my cart before I could actually get the order to process.
Side note: 90% of people buying one will be flipping it on eBay. If it's anything like the 20th edition, they'll be selling for $500 on Sony's website and then re-selling on eBay for $3,000+ minutes later.
