Stockpile for cataclysm?

So what should you stockpile for cataclysm? i would say low level trade goods and low level gear, because people will want their alts to have the best gear they can get and they will be power leveling the alts professions. But also the thing i think is the smartest to stock is bags both neatherweave bags and frostweave bags, the people that level their alt want to have big bags so they don't need to go back and sell stuff all the time but can just keep going. So i would say bags,trade goods and gear is good for stocking until cataclysm
