Portals

From Computer Gaming World Dec 2005: "Things will get even crazier once you open portals into other worlds—three [of these] zones are already planned for the expansion, with seven total that Blizzard knows about."

Chris Metzen revealed in the Developer Panels that Illidan closed all the Dark Portals of Outland. Nevertheless, MagusRogue, a World of Warcraft RPG Game Designer from White-Wolf revealed the following: "The portals were shut down by Illidan, actually. However, some of the quests in the Burning Crusade Expansion have you re-opening these and going to new dimensions, fighting the legion in new worlds. Should be awesome."

"One of the things we're most excited about," says Metzen, "is the chance to create environments unlike anything you've seen in previous games. We really want to ramp it up for the players now. We're saying, 'Hey, you've graduated, you're over level 60 now, so let's get crazy with some really alien worlds and creatures." Even better, this is something that's infinitely expandable for us in updates and expansions down the line. There can always be more portal worlds."
