If you die throughout a Diablo 4 PvP fight and you are in Hardcore mode, you're dead permanently.
We've known normal deaths, that's, deaths that occur during PvE battles would lead to permadeath, however, we know you will need to start a new character should you die during PvP battles in Hardcore mode. Diablo community director Adam Fletcher revealed just as much on Twitter.
Honestly, this is one way. If you're choosing a mode that makes it explicitly clear that any deaths you suffer are going to be permanent, there is no reason for that same inherent risk to not extend to PvP. It was this way in the first couple of Diablo games, but Diablo 3 changed by using its segregated battle arena fights, which notably don't lead to permadeath for that loser. Diablo 4, since it's darker, as the grittier atmosphere might suggest, is a return to true hardcore PvP.
Today's lengthy developer livestream also revealed another Diablo 4 open beta happening from May 12-14, providing you with (presumably) the last chance to take part in the game in front of its full June 6 launch. All of the Diablo 4 beta changes revealed so far are going to be in effect within the May beta, to help you see for yourself what's not the same as the last beta weekends. Furthermore, the Diablo 4 beta rewards will once more be available to earn by reaching various milestones.
In related news, Blizzard also said today that Diablo 4's PvP zones are "not a spot for honor" and won't shield you from bigger squads.
