I don't think it's sold out. I think they just turned off the entire PS5 store because people were adding to cart before orders officially opened.
You can't even see the PS5 splash front page anymore: https://www.amazon.com/PlayStation-5-Console/dp/B08FC5L3RG/ just shows me dog pics
The only one with that name I could find is the normal one (granted, I can't search on amazon directly as they keep insisting to show me only the results of my area)
