Virtual wallet coming to Blizzard's Battle.net "in the weeks ahead"
Blizzard has announced it will soon introduce a new feature called Battle.net Balance. It's basically a virtual wallet Battle.net users can add funds to, using various payment methods. The user can then dip into the wallet to purchase World of Warcraft digital products, and soon, purchase items and store various earnings from Diablo III’s auction house into the wallet.
The new Battle.net Balance feature will be "rolled out" in the weeks ahead, according to the firm, and you can check out the FAQ on the new system through here.
