It is coming, but not started, yet.
I can tell you, if you have a controller, that Bluestacks will run Exiled Kingdoms fantastically if you have at least a Core i3 and 4GB of RAM.
Our developer for EK is currently focusing on the Android and IOS platforms right now.
I would guess it will come after version 1.0x (Public release plus a couple hotfixes), and since I'm guessing, you could take it with a grain of salt.
I am going to make a tutorial on how to play the game with Bluestacks very soon for people who just want to play it now on PC.
