Diablo 3 will not require a constant internet connection for local multiplayer on the PS3 or PS4, Blizzard production director John Hight has confirmed. "You can have four people on the same screen - no split-screen, we just zoom the camera out. Or if you're offline," he tells Geoff Keighley on GameTrailers.
It's around the two-minute mark where Hight goes into the changes to Diablo 3 for PS3 and PS4 in the episode above – specifically, the talk about the camera and local multiplayer. Hight reveals there's also a new evasion ability to help players quickly escape large encounters.
Diablo 3 launched on the PC and Mac OSX with a required connection to Blizzard's Battle.net service, even when playing single-player. Blizzard previously revealed the PS3/PS4 versions will have a different UI and feature all major PC updates.
