I haven't heard much on the matter other than there being a separate mode for pvp and there will be arena teams or something (unlike D2 which players just battled anywhere if pvp was enabled) Will there be entire new maps for players to pvp on, and will it still be restricted to 4 players in a match? And if there is a arena mode will it also be on separate maps and capped to 4 players? And will there be game modes other than just death match?
Ideally I'd like it to have separate pvp maps with more than 4 players, as well as the classic Diablo 2 pvp to be enabled in co-op.
(I'm not sure if there is official info on this from blizzard, i haven't come across any yet)
