Sony has announced the new firmware update 1.51 for PlayStation 4 and labeled as coming soon & sooner it is available for download. By seeing the update we believe that the update coming to next-generation consoles by the end of the week.
According to the PS Blog,
“Later today, the next system software update for PlayStation 4 (version 1.51) will be available. With this minor required update, stability of system software has been improved. In addition, minor refinements to elements of the system UI (such as clearly indicating when a user downloads a game and a game patch at the same time) have been introduced.
In the North American region, automatic downloads for system and game updates are enabled by default when PS4 is in stand-by mode. Once system software update 1.51 is available later tonight, your PS4 will automatically download it, enabling you to update quickly and easily.”
If your PS4 is in stand-by mode, then you can expect that the 1.51 firmware already downloaded onto your console and if you don’t have PS4 in stand-by mode you will receive a prompt message the next time you turn on your console stating that update is being downloaded.[Source] PS4 Blog
