Cataclysm is coming - Are you prepared?

Greetings

It's been quite a while since I last had the time to write another post, mostly due to a lot of work at school (and partially due to being addicted to Starcraft 2).

Today I want to discuss somewhat the same as everyone else - namely Cataclysm!
It has recently been announced that the official date of release will be December 7th. For the players that are into the gold making game, this means one thing; preparations!

But what really should we do to fully prepare ourselves? I will be going into what my personal preparations will be, and I hope any eventual readers might fill in with whatever they are doing.

Stockpiling

Commonly known, there will be inflation on lots of items in the World of Warcraft when Cataclysm launches. Common players / farmers will no longer farm ores/herbs/leathers/cloth from Wotlk content, but rather move on to the Cataclysm ones. You might ask yourself;

"What will that do with the economy?".
Certain items that no longer will have a steady supply, which still are going to be in great demand due to newly rolled Goblins / Worgens, will increase their value. Also, rare items, that no longer will be farmed on a good basis, will inflate and increase massively in value.

"What should I do to get a slice of the cake?"
If you yet haven't started stockpiling materials and items, that will increase their value, the time to start sure is nigh. Players will be dumping tons of items on the Auction House now that they know that Cataclysm is coming. This is where you come in. This is the time you got to buy up all the cheap items that you will profit by saving into Cataclysm.

"Well then, which items should I stockpile?"
Any items that will be low on supply and high on demand is items that generally will be great to stockpile. As for my own part, I have been focusing mainly on stockpiling large amounts of cheap:
- Saronite Ore / Bar
- Cobalt Ore / Bar
- Herbs (from ~STV quality and up)
- Enchanting materials from BC and LK
- Uncommon LK gems
- Rare LK gems
- Vendor pets (Stormspire, Dalaran, Horde and Alliance faction cities, Tournament pets)
- Netherweave Cloth as Bolts

These are all items that will be in high demand during Cataclysm, with most of them having rather low supply. All ores/bars/herbs/ench. mats/gems will be wanted by newly rolled Goblins / Worgens to skill their professions up quickly. I expect to be selling thousands of bags during early Cataclysm, hopefully for more than 30g each, which would mean roughly 1000% profit on my server. The Vendor Pets will decrease in supply, and rise in demand, due to newly rolled Goblins / Worgens.
The main reason I do not stockpile Leather: Most Worgens will pick Skinning/LW due to passive racials, which will cause the prices to drop quickly.

So, what are you saving up for Cataclysm?
