If its consider the same, because its PS4 and the same platform, then it could well become the best selling console of all times. 400 USS for such a powerfull console now and let say 250 for the old one will make sony sell these consoles like pancakes. Think about every 3rd wolrd country where people cant afford a PS4 for 400 USS. They will buy the old PS4 for 250 for sure.
