Here are the Warcraft RTS games;
Warcraft I Orcs&Humans
Warcraft II Tides of Darkness, Beyond the Dark Portal
Warcraft III Reign of Chaos, The Frozen Throne
Warcraft IV Warlords of Draenor?
Here is the HearthStone;
HearthStone; Heroes of Azeroth, Warlords of Draenor
I am not sure what the trademarked Warlords of Draenor will be for.
Can be anything, but it would be great if we wait for BlizzCon.
