For the people testing on beta Cataclysm, have you noticed any drastic price increases over prices of Northrend? I remember how 100 gold by level 40 used to be difficult. Now, I spend over 100 gold on the AH daily. I especially remember how suprised I was by the high cost of taxi services on Northrend compared to Outland. I know the mining, herbs, and new professional recipes will command a top price when the expansion comes out, but I wondered about the training, travel, and new flying training (if any).
