World Of Warcraft: Under Development Page Update

Blizzard stated...

Player vs. Player Honor System
The PvP Honor System is in its final phase of testing. We are currently running stress tests with data taken from live realms. These stress tests allow us to catch any unforeseen problems that can occur when the system begins calculating data from hundreds of thousands of players at one time. As soon as we gather enough information and are comfortable with the performance, we will activate the Honor System in a patch.

Battleground System
Battlegrounds are currently undergoing extensive internal testing. Once we are happy with our internal playtests, we will open up an external test realm so we can begin testing Battlegrounds in a live environment with existing players. Please note that we are still working out the details of the test realm and we will release more information as soon as it becomes available.

Instead of holding back already-finished content and necessary bug fixes for a combined patch with these systems, we decided to split them into separate patches. This lets us present new content immediately while still allowing us to refine these two new systems. The Honor System and Battlegrounds will be introduced in a later patch in the future, and might not be unveiled at the same time. We will reveal more information as it becomes available. Thank you for your patience.

Once again, we thank all of you for spending your time with us, and we wish you luck on your adventures in Azeroth.
