Hearthstone Fourth Quarter Theory (Maybe some spoilers, its just a theory though)

I was looking over Hearthstones "A Year of Mammoth Proportions" post where they discussed what all was happening during the Year of the Mammoth. Looking at the expansion images on the page, its easy to see what the first two expansions were referencing to now that they are released. The first with its jungle theme was Un'goro and the second being Knights of the Frozen Throne with the Death Knight Runes. But the third is an odd one, at least to me. I made a theory while talking with a friend. After looking closely, it looked like it was an expansion that would be related to money or treasure. Even though its a stretch, after some color saturation to the third expansions picture, it looks like it could be related to Blingtron in some way. The piles in it look like piles of gold and gems and are similar to the piles of gold and gems in the Blingtron art.

This link is to a picture I made, with some zoom on the third expansion image along with the color saturation and comparison to the Blingtron art from Hearthstone like I said.

It could be an expansion based off of the world the Blingtrons go to, which is what my theory is (though it's a stretch). What do you think?
