Assuming the vote passed(I see no reason why it wouldn't have) I believe it should go live at 2pm pacific time.
Yes... I'm aware... the announcement was incorrect. It was a template that was never adjusted to reflect the changes made 6 months ago to the release timing for both Ragefire and Lockjaw. Ngreth posted like 3 months ago that it was 2pm PT on August 20th. I posted in a few different places but was able to confirm with someone that the post was likely in error (since the xpac didn't launch this morning at 12:01am, that's pretty much confirmed).
