Party voice chat on PlayStation 4 will support up to eight players, just like the PlayStation Vita, social media manager Sid Shuman confirmed in the comments section of a Killzone: Shadow Fall post on the PlayStation Blog.
"Party Voice Chat will support up to 8 players on PS4, like PS Vita," Shuman wrote.
The PS4 will also feature cross-platform party chat, allowing console players to communicate with those on the PS Vita.

PS4's DualShock 4 controller has digital face buttons rather than the pressure sensitive analogue ones found on previous PlayStation pads.
Pressure sensitive buttons allow designers to assign multiple functions to a button based on the pressure applied by the player, or change on-screen behaviour depending on how strongly the button is pressed.
"With the DualShock 3, we were able to get analog data, which games didn't really use. For DualShock 4, we deleted that, and now it's all digital," he said. "The mechanism inside is a little different, and the data that games get is different."
