Calling all PS4 fans! Before we launch our next major system software update, were running a beta program to test its functionality. If youd like to get a sneak peek at the features of the new system software, and help us with feedback on ways to improve it, sign up today.
You can sign up to be a beta tester here. You will need a PS4 system (of course), an Internet connection, and a master account sub-accounts cannot participate in the program. Make sure youre a member of the PlayStation Forums in advance to get access to our beta forums. Also, beta testers will be able to roll back to the previous PS4 system software update (v2.57) anytime.
The beta program will start in early September, and well have more information on the new features included at that time. We are accepting a limited number of beta testers, so if youre interested, sign up sooner rather than later.
Thanks in advance for helping test the system software update your feedback will go a long way toward making this even better.
