So apparently, unlike most people believed (myself included), we're not having the broken shore event in the pre-patch, rather, we'll have it by the time Legion officially hits live.
Saddens greatly as I was looking forward to this event the most out of all novelties we're getting in the pre-patch. Oh well!
Proof: World of Warcraft facebook comment "Exactly, the Broken Shore intro will indeed only become available with Legion."
