people that think WoW Classic won't have updated graphics and old graphics intergrated are fucking hilarious. "Oh no, we want old graphics because that's classic!"
Don't worry, you'll get it. And WE get to play with new graphics in the mean time.
Some how you purists have gotten it in your heads that CLASSIC WoW means old school graphics. One of the first and only things that said is that they want to make it a Blizzard worthy product. So that means polished, up to date graphics. But considering the whining you purists manage to put out about it, there's no doubt they'll take care of you as well.
