Blizzard is preparting World of Warcraft patch 2.4.3, and it isn't a very big patch, as you already might have guessed when they didn't call it 2.5. Things like changing the level at which you get your first mount from 40 to 30, and reducing the cost accordingly would have made big waves in 2005, but raise barely a yawn in 2008. Much more interesting is what happens at the other end of the game, for level 70 characters: Haris Pilton is selling luxury handbags. Gigantique 22 slot bags for 1,200 gold, to be exact. Not unique, in case you want to buy 4 for yourself and another 7 for your bank. If you close your right eye and squint with your left eye, the pearls on the luxury handbag form the word "money sink". :)
In the real world luxury handbags are one of the most faked items on the black market. In my opinion that is because while women love to show off, they are also realistic enough to not want to pay the price for an original. For the WoW virtual version I can only advise you to pursue a similar strategy. I am pretty certain that Wrath of the Lich King will have easier to get 22 slot bags, most probably in form of a tailoring recipe for level 80. And as these will be a lot cheaper than the Haris Pilton Gigantique 22 slot bags, I'd recommend keeping your money and waiting for those cheap bags. After all, in WoW nobody can see what brand of bag you are wearing.
