J Allen Brack, senior producer of Wrath of the Lich King: At the start of each expansion, we've said, "do we want to do a graphical update?" EverQuest and Ultima Online are the two games that tried that, but most players ended up preferring the original art. That doesn't feel good as a developer - to spend all that time on new art, and to hear "what you had before was better". There's not really a clear path for us to work out what the right plan for us is.

Our approach now is to continue to expand and make cool effects for players with high-end videocards and high-end processors, as long as there's some kind of fall-back system for those that don't have the hardware. We have plans to increase the draw distance: we doubled the maximum draw distance in The Burning Crusade, and we'd like to increase it again. I don't know if we'll be able to double it again, though.
