Dan - Hakuna Matata! What a wonderful phrase! ♫ — 22:06, August 3, 2010 (UTC)
Wikipedia shouldn't be trusted as a reliable source. That part of the article looks like speculation, as the editor who added the sentence about the new worlds didn't provide a source.
LapisScarab - You accept darkness, yet choose to live in the light. So why is it that you loathe us who teeter on the edge of nothing? We who were turned away by both light and dark - never given a choice? TALK - That may be... however, what other choice might we have had?
There hasn't been any word one what worlds are going to be in the game yet, other than the screenshots.
