WoW looks the way it does because we chose a specific art style, but we also developed the game with specific hardware requirements in mind. We've purposefully designed the game to appeal and run well on an extremely wide range of machines.
While it's possible that at some point in the future there may be a graphics pass updating texture resolutions and polygon counts, I think that you'll see with Wrath of the Lich King as you did with Burning Crusade, is that we're continuing to improve our technique and art style while still remaining within those same system hardware requirements.
There's still juice left to squeeze with the current engine and self-imposed constraints.
