One lucky individual got his PS4 ahead of the launch and isnít shy in sharing the details openly with the public. Since Shuhei Yoshida, President of Worldwide Studios at Sony, clarified that even if someone receives their PS4 ahead of the launch, the console wonít be banned by Sony for going online. However, to activate many of the features and functionality of the PS4, one needs to download a Day One update for the PS4 which is around 300MB in size. Shuhei Yoshida also clarified that a person can play games on the PS4 even without the Day One update.cjcool804 states that without the update he cannot log in to his PSN/SEN ID and the update is still not live for the PS4 for direct download on the console and more so, cannot even use the browser on the PS4. He can, however, play games on the PlayStation 4 without any update or internet connection required.
