Currently, we expect to release World of Warcraft Patch 5.3: Escalation next week on Tuesday, May 21st!
If you follow @Bahska on twitter you will know i said this a week ago. It was pretty obvious. All the "hype" interviews, excited CM's dropping hints (Even the ptr blue Sapperwix) and the fact a release build went up on the ptr on the 16rh.
Sure its always good to wait for a confirmation but these last few times Blizzard has had issues holding in there excitement. ;)
Not a bad thing of course, im glad to see Blizzard is still excited to make content for there 9 year old game. Even with the relatively bad news with subs.
