World of Warcraft: Legion, the upcoming expansion, was only recently announced at Gamescom, but it seems we might be less than a year out from the expansion.
According to the small print of this now inaccessible picture on Battle.net, which was caught by Reddit (via VG247), the game is coming September 21st, 2016 (Or before). It also reveals a $49.99 base price point. This hasn't been confirmed yet, so do keep a little scepticism.
BlizzCon starts today, so I assume we will hear something soon on this. I'll update you once we know more on this front.
