Just another theory. I think that they won't plan to do 2 expansions related to only one new continent like Kul'tiras. The 1st one to me looks like a witches theme from kul tiras or the most viable theory that is Duskwood (and will include fel corrupted creatures rather than connected to the old gods). But at least one of them will include more pirates to the game because Patches wasn't nerfed in vain, there must be a reason why they nerfed it even if it was moving to Wild. And that's why I belive the third expansion will be related to pirates. 

He is using half finger gloves , what if he is on a boat to Kul´Tiras? Maybe that's not snow and it's fog o_o

When does Dave find the new expansion? 

I am sure that all this hints are somehow leading us to different way and answer is Dun Morogh

Judging by the teaser orb, Duskwood seems more likely than Crystalsong Forest to me.

Perhaps we’ll see the new tribe Worgen and neutral legendaries like Goldrinn – your worgens have +2 attack and Baron Silverlaine – deal 2 damage to all worgens, plus some worgen minions like Bloodmoon Initiate and Bloodmoon Raider?

And how about Mage Legenday Archmage Arugal - your secrets cost (1), or minions like Raven Hill Grave Robber, Malvolent Dark Rider and Corpseweed?

Grinding gold and preparing for an exciting expansion J

I don't know if this has to do with the new expansion

but I would like to see Dragons in Shaman.

I mean Ebon Dragonsmith is a good card.

Cobalt Scalebane buffs totems.

Bone Drake gets priest dragons and Sindragosa.

That's what I want in the new expansion if anyone cares. 

I might be wrong, but it seems you seldom play shaman since you are willing irrational and unnecessary things to be given to it. What shaman really needs is strong efficient bordclears and good card draw. Right now shaman lacks both things and thus can't be a decent control class and is locked in atrocious "swarm the board" aggro style in hope to close up the game with Bloodlust. Jades are rotating out, Evolve is rotating out, N'Zoth, the Corruptor as well - and shaman is left only with elementals and joke freeze.

Snow in the Woods

4 months is just still way too long between new content & getting dripfeeded for a month sucks as well

Next expansion is: burning man festival...

What about Terokkar Forest?  If you look at the image, the Raven is standing by a tree that has a green crystal next to it that looks like the crystals all around that region.  

the green gems are jades, they like jades so much they are bringing them back but only for druid :v)

So do we get the first teaser reveal tomorrow or Friday or Monday?

 Could be a winterspring expansion. Furbolgs are pretty cool.

The word outdoors reminds me of the Grove Tender quote "ah the great outdoors"... druid expansion confirmed!?!!

The art for this expansion could be something emerald-dreamy, though I doubt that the tweet refers to the voice line.

Quote from ThunderHS >>

The return of the Freeze classes?

Exactly, and I bet the cards will have a spooky/horror theme.

Everyone, brace yourself for the return of Freeze Shaman! Kappa
