This is a curious development. Patch 3.3.5 has been undergoing PTR testing for a couple of weeks now, but there has not been any testing yet of the new Battle.net 2.0 communications interface. As many of you know, this interface will allow players to keep their 'friends list' via Real ID and monitor the status and chat with their friends across games including Starcraft II.
Since this change affects multiple platforms, not just WoW, they'll be phasing the system in at a different time. Unfortunately for players overseas they're going to have to wait a week to get the patch. This will no doubt have guilds seeking world first titles in the Ruby Sanctum up in arms, but what can you do?
It's also interesting to note that Starcraft II will be going down for Battle.net upgrades beginning next week. It's highly likely that those upgrades and the release of SC2 will coincide with the release of 3.3.5 so we could be looking at a patch as soon as early July.
The Vote Kick system has been controversial since the beginning, and a change like this was a long time coming. This change will essentially reward players that vote kick only when necessary rather than doing it maliciously while providing protection against griefers. Good change here.
