I've checked the druid of the talon quotes from W3 and the mission where you gain the druids of the talon in the night elf campaign. I can't find this quote, can anyone else?
http://www.escapistmagazine.com/news...ts-Patch-4-3.5Greg Street: Remarkably, we keep creating continents, whole plots, when we need new ones. And there's a greater multi-verse outside of that one planet. We went to a different place in the Burning Crusade expansion and we can easily do that again, there's other dimensions, the Emerald Dream to explore. We have the mechanic with the Caverns of Time we're talking about what if we made an expansion that was all back in time. Let players play at the height of the Night Elf civilization, for example, that would be a cool expansion. So I'm not worried about running out of ideas any time soon.
