Using Basic Suppy/Demand analysis, the demand curve for Frozen orbs will increase while the supply curve should stay the same. Prices will rise and volume (as sold over the AH) will increase.

For the trade goods, the demand curve isn't really affected, but the supply curve will increase, leading to lower prices and higher volume. Ultimately, the price of frozen orbs will roughly equate to the most expensive trade good, which will likely be eternal fire or frost lotus, potentially all three evening out. If frost lotus don't significantly drop, I don't foresee eternal prices fluctuating that much.

The need.greed dynamic for orbs might fluctuate a bit in randoms though.

I'd be more concerened with the number of people who have their wealth tied up in the high qulity cloths and titansteel. Sell that stuff before 0 day, because prices are going to tank, and pray to God you can hock your finished products before they tank as well.
