There was a press day around the world starting Thursday, and from what I know also on Friday that showcased Warlords of Draenor to several fan sites and other related media outlets.
Not found or heard anything Warlock specific yet, but I figure if we hear anything in the coming days we may as well have a topic for it allready.
1 thing I did come across just now is a video by someone who has clearly not played a Warlock seriously recently, but it did have this nice shot of the talents in it:
As you can see, nothing changed from Blizzcon apparently. So the talents as we saw them then should still look and work the same.
(You can see those talents in this first post of the Blizzcon chat thread. Brusalk allready corrected my mistake in the second post of this thread, showing there IS a change. And thanks to Valyna we have a screenshot of where the person accidentily moused over Cataclysm talent, showing that nothing changed about that talent. Screenie of it provided by Valyna)
Fur fullness sake, you can find the dubious Warlock video (which contains some spoilers and a look at the first Horde zone as well) here: http://www.youtube.com/watch?v=Hn1OeGG9idI
Anyway, that's what I came across, feel free to chat about the lack of changes or anything you come across in the coming days here in this thread.
