By now one thing is clear. The launch of PS5 preorders was complete chaos. Sony has promised plenty of advanced notice and that preorders would not be a surprise. They even had a secret mailing list where they would pick and choose people to preorder the console before anyone else. Then in a live event Sony announced preorders would begin the next day. Retailers didn’t get the memo.
I believe it was Walmart who started the chaos. They took to Twitter immediately after the Sony press conference with a tweet something like “Make you wait for a PS5? Naw that’s not us. Order your PS5 now.”
