When you fire up Hearthstone and you see the main menu, you’re faced with three options: Play, where you can get into a match, Solo Adventures, where you can explore the dungeons like Naxrammas, and Arena, where you can get special rewards by winning with arena decks. Below Arena, there’s an empty slot.
Blizzard’s going to fill it with… something.

Blizzard teased the new addition to the options in a short clip on Twitter, but the new button is blank. Since each of the existing three buttons is for a game mode, it seems likely that the new one heralds another mode.
Expect Blizzard to spill the beans soon, but in the mean time, what do you think it is?
