The World of Warcraft: Wrath of the Lich King Interview on Eurogamer is another conversation from the Leipzig show with designer Tom Chilton and producer J. Allen Brack about the upcoming WoW expansion. They talk about new graphics options in the expansion, but when asked about how to entirely replace an aging graphics engine in an MMORPG, they point out that both Ultima Online and EverQuest created new graphics engines that some users refused to adopt because of performance drop-offs and other issues. In spite of that, Brack admits that they will "probably" need a "graphical update from the ground up at some point," and he is "positive we'll talk about it next expansion." Thanks IncGamers.
