As we approach the end of the Cataclysm expansion -- there are maybe four months left -- playing the Auction House gets a bit trickier. There's less enthusiasm on the part of buyers. More scary, though, is that the launch of Mists of Pandaria is about to render a lot of markets obsolete. It happened in Wrath and in The Burning Crusade too -- those potions and flasks that were top of the line suddenly became worthless. Gear that once cost thousands of gold could be had for hundreds. It's the nature of our in-game hobby. If you sit on stock, you're going to lose a fortune. (Shamefully, it happened to me out of laziness.)
But not everything is set to crash. A few select items are going to increase in value, if not in the days leading up to MoP, then shortly after launch. These are the items you need to fill your bank tabs with. But which ones are they? What should you sell ASAP, and what should you buy?
