What do you think guys?? This is what they did with hagatha in the last expansion. They did a little teaser of him

 Nah .... it is probably nothing ...........

So there's been a lot of talk about the hero power but about the battlecry? What could it possibly be? 

since warrior DK already has a weapon, it will be something different

It says "THE BOSS" on the sign above it, which really makes me think they will make a new single player mode this expansion, with this card as final boss. Also makes sense because that is what they did with hagatha and hagatha was released in a very similar way.

 Although it was already obvious that this would be the token hero card of the expansion, that's a very good point. 

what about a giant boom-bot that summons 2 tiny Dr. booms.. 

7 mana gain 7 armour summon a boombot for each enemy minion - heropower summon 1 or 2 boombots at random. Something like that would be a cool card. You can have a bad turn where you summon 1 boombot that deals only 1 damage or two boombots that do 8 damage together. Perhaps it is a tick to strong but hey look at the other DK and then judge again xD

Hero Power: Discover two mechs, merge them into one (like Deathstalker Rexar's zombeasts)
