Diablo III Forum Tidbits

Blizzard poster Bashiok passed on by the WoW Forums to mention that Diablo III has a big focus on cooperative gameplay.
We have a large focus on cooperative play for Diablo III, and the mechanics and design decisions related to multiplayer are likely going to be based on supporting and encouraging it as much as possible, and not breaking it down.

That doesn't mean that PvP won't have its own focus, but those are details and features we aren't yet discussing.
