Bigger party sizes are an oft-requested feature across all platforms, and Xbox One saw an increase from eight to 12 back in 2015 -- so it's taken Sony a while to catch up. It's still early days though -- right now you can only sign up for the chance to participate in the update's Preview Program. US testers that make the cut will also get access to PlayStation's new chat transcription feature, which converts Party voice chat to text, and text to dialogue spoken aloud by a robot, on the PS4 Second Screen app.
