Probably the most interesting portion of the interview is the sadly brief discussion of Blizzard's POSA (point of sale activation) cards, known as Battle.net Balance Cards. These cards are similar to the game time cards most WoW players are likely familiar with, but rather than add time to your WoW account, they add money to your Battle.net account in general, which you can use to add time to your WoW game or purchase other Blizzard games and so on.
So far, these cards don't seem to be readily available in the US as in the EU, but I have heard rumors of people finding them in GameStop from time to time, so who knows. For those of you who are wary about using a credit card online, or who just might like other options for adding money to your Battle.net account, they might be worth looking into. You can check out the EU Battle.net Balance Card FAQ for further information if you're interested.
