Recently and quietly amidst all the loud chatter in the wake of the High Isle Chapter launch, Zenimax Online Studios hinted at the biggest changes for PvP (and PvP'ers) perhaps since 2017 (February 2019 saw to the addition of 1 Battlegrounds map)

Gina Bruno on the forums stated:

Hi everyone,
While all the aforementioned backend work is still ongoing, including sourcing the new hardware for PC EU and console megaservers, we did want to share a couple changes coming to PvP that will be going into Update 35.

First, we’re implementing some tech that will allow us to easily activate special Battleground weekends, without requiring any server downtime to start or stop. The plan will be to feature a single game mode over several days and also grant 25% increased AP while participating.

Outside of these recurring Battleground features, we’re also planning to increase the amount of XP you can earn doing various types of PvP activities within Cyrodiil and Imperial City including killing monsters and other player characters, or completing quests in these areas.

We look forward to testing everything out in the next PTS cycle so we can officially kick these off once Update 35 launches.
