During today's ESO Live show, it was mentioned that the first of the fixes is coming in update 1.5.6 to address the lag issues in Cyrodiil. The investigation is continuing and there will be more fixes coming in future patches. Update 1.5.6 is tentatively scheduled to arrive on Monday, November 24.
While some of the lag problems will probably still exist to some degree after Monday, we should see some performance and responsiveness improvement provided the patch works. To me, it sounded like things will be better but won't be 100% yet, Lag/freezes when weapon swapping may also be fixed on Monday.
Additionally, some changes related to audio cues in combat (specifically audio for your own attacks) will be distinguishable from the combat sounds of others around you.
All of this discussion starts around 56:10.

Also, it was mentioned a couple of minutes prior to the lag fixes that the devs are still working on changes to forward camps, the latest of which is a respawn timer which would be similar to the amount of time needed to travel from a nearby keep. No ETA was given for these changes.
No release timetable or future PVP changes were discussed for Update 6.
