Game Director Tom Chilton confirmed that the team is already hard at work at the follow-up to Warlords of Draenor. "We already have zones in production for it," he said to Gameplanet, adding that the team will also be looking at the theme for the seventh expansion "over the next several months."
Chilton indicated that World of Warcraft has a long life yet to come: "Beyond that, there are about six or seven different ideas for expansions that we can take elements of and say, 'You know what? Let's take that and put it in this one for our next expansion after the next one.' [...] As long as there are enough players demanding that we make more content then we're likely to do so. I think it'll be quite a while before the financials indicate that it's just not worth doing anymore."
