The official World of Warcraft Twitter account just confirmed the end of PvP Season 14 would take place as estimated, on Tuesday February 18.
PvP Season 14 is currently scheduled to conclude with next week's standard realm maintenance. Good luck! http://t.co/MxsaULpaE1- World of Warcraft (@Warcraft) February 15, 2014
As Brian Holinka has tweeted in the past, the end of the PvP season has, in recent instances, indicated the release of the coinciding patch. Throughout Mists of Pandaria, this is the pattern that has been followed, so it seems likely that patch 5.4.7 will be no exception. You can check out all our patch 5.4.7 coverage in the meantime.
WoW Insider also put together a short guide to what you should be doing to prepare for the end of the PvP season, so get those wins in for that mount, cap out that honor by killing those rares, and be ready!
