Amazon UK did a naughty and listed the PS5 pre orders briefly before realizing their mistake.
The pre order price was 599 pounds. They also listed some games (with black covers) before removing them.
A supposed PlayStation 5 console listing has been spotted on Amazon UK, and apparently, someone on hotukdeals was able to push through and place an order. The listing specifically mentions that it's a 2TB model, and the price is £599.
+1I found storage not to be an issue once I stopped installing games I wont play for ages etc, stick to a couple at a time.
Or an hour earlier if you want some extra hype building with Summer Game Fest / Geoff Keighley or IGN.
