According to new interview that is on main page 6.2 will be Tanaan Jugle. No Falahron or something else. Here is why:
1) https://twitter.com/WarcraftDevs/sta...71404623810560
2)3)The Garrison Campaign will set up the invasion of Tanaan Jungle, so there isn't any more story to tell in Patch 6.1. There are also players still working their way through the Garrison Campaign now, so this break will give them a chance to catch up.They consider Tanaan as next new zone.Being able to fly in most of Draenor but not Tanaan Jungle is one possibility.
What do you think? . It is odd that only 2 raid tiers. Kinda short. Missing middle raid tier like ToT , Firelands
