It looks like the World of Warcraft movie is still a long way off. According to Blizzard’s vice president of creative development Chris Metzen, "We’re still kind of getting it together with [Sam] Raimi and his team and jamming on themes that we want to chase." So, in Hollywood lingo, it seems like it's in the early, pre-script stage.
Here's the full quote from Metzen for you to parse and understand as you like:
"We’ve been through a number of story meetings, and we’re still kind of getting it together with Raimi and his team and jamming on themes that we want to chase. We’re kinda getting a lot of values together – what kind of story we want to tell, what do we want people to feel, what is the best way to look at this big franchise. We had had some script iterations previous to Raimi coming on board that were cool, that had some really good bits – sometimes a little too overcooked or a little too undercooked. We’re still trying to feel out that space, so as he came in he wanted to have fresh eyes and look at the content of Warcraft in such a way as to dig out what will most people feel: 'Oh, I get it, that matches my expectations when I played.' You can aim the camera in a hundred different directions in a place like Warcraft so it’s kind of finding that right one."
