Pretty interesting. All out zerg action and no loot. Certainly a change. Blizzard is definitely trying to get everyone who doesnt like the WoW setup, and a lot who do, to play WoS.
I belive all of the pics are from the starcraft:ghost multiplayer (though slightly modified to inclue the action bars and stuff). They had the multiplayer demo at blizzcon and this looks the exact same, but yeah they did the pics well!
My friend in Australia really wants to get a new boomerang, but he just can't seem to throw the old one away.
