The always awesome Alice Taylor from Wonderland was at the Hollywood and Games Summit this past week, and Blizzard's Rob Pardo made an appearance in a panel about creating a "parallel experience" between entertainment media and MMOs. Alice put up summaries of the various points made, and the result is a pretty interesting read into how Blizzard is working on their upcoming Warcraft movie.
The whole panel is a good read (reps from MTV and Sony also make appearances to talk about how they're taking audiences across media), but Pardo specifically makes the point that in whatever media you're in, you have to balance how you're using that media against how you're using the intellectual property the media is based on. "Demographics," he says, "follow the IP," so Blizzard clearly thinks that if a Warcraft movie is released, that Warcraft players will run to see it in droves. But at the same time, he says the media must define how you use the IP-- Warcraft RTS is a different experience than WoW, and WoW will be (supposedly) a different experience than a Warcraft movie. He does want to make sure "the epic scale of the IP shows up in that movie."
He also speaks to Blizzard's plans to make "episodic content" for WoW rather than "boxed content," and says that they haven't delivered content as fast as they've wanted to yet. But he also claims, "We've got our head round it now." So maybe they really will have a new expansion for us ready on time next year.
