Personally, I'm all for the early pre-order access requirements. They still open at a later date for others, and the requirements get lessened over the week or so for the NSO lot. Unsure how successful it will be in combatting scalpers, but hopefully it will help in avoiding a PS5 release situation, where you couldn't get anything for a good year+ as scalpers had picked them up and sold them for double the price.
Even 2nd hand stores were buying in PS5s for more than their buying price, just incentivising it further. (yes, I did work in one at the time, and yes people would buy just to sell. No, I do not agree with the pricing or scalping from anyone)
You can request a pre order from Amazon now though, and getting through alternate suppliers that others may not think of first (Very, Smyths etc) often yield good results.
