Hackers also have no way to get your credit card info off your WoW account.
Although I hate the idea of a real money auction house, it will probably dramatically reduce the profitability of gold/item selling by flooding the market. Right now the black market nature of gold selling drives the price up a lot, but the rate of return per hour is still so low that it's only worth doing if you live in a poor country. Cut out the black market, and I doubt it will be worth doing for anyone. This should dramaticaly reduce the amount of account hacking. Whether it will be worth the cost is a completely different question.
