Everyone can sign up at least, which certainly doesn't guarantee a spot, but it's better than nothing. With PS4 System Software 3.00 apparently in the wild and testing and this program kicking off next month, we're hoping to see that pushed out to all users soon.
Hop on over to the official registration site, here to register.
Read on for the info direct from the PS Blog regarding the program.
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 you’re 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 we’ll have more information on the new features included at that time. We are accepting a limited number of beta testers, so if you’re 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.
