As a fan of Arenas, and this being a PvP esque expansion. Has there been any update on what they're doing for PvP besides world pvp?

World pvp has its own allure but, 3's is where the action is at! I Haven't been keeping up to date on BFA up until now, so has there been any info / announcements on how they're handling instanced pvp in arenas or even rated BGs?
