From the latest 7.1.5 build:

• TOKEN_CONSUMABLE_DESCRIPTION_30_DAYS_BALANCE (New) – Use: Adds 30 days of game time to your World of Warcraft account or %s to your Battle.net Balance.

Time will tell how much the WoW Tokens convert into. Many seem to think it will convert into a standard $15 amount, same as a normal subscription. That makes a sort of elegant sense. I was kinda hoping that it converts into enough to cover an entire Server Transfer (currently the outrageous $25), as that means moving two toons would require four Tokens with some remainder, or perhaps three and a $5 bill thrown in. Of course, that’s not going to happen given they went the Battle.net balance route, unless Server Transfer costs go down.

Anyway, when I got wind of the WoW Token update, I quickly bought up as many Tokens as I could:

I have five WoW Tokens on the druid now, and presumably five more somewhere. Current prices?

Nearly a 6000g discount.

Of course, it’s always possible that Blizzard doesn’t make current WoW Tokens “backwards compatible” with their new functions. In which case… shit. I guess I have 10 months of free WoW time? That said, I’m pretty sure Blizzard isn’t going to confuse the issue by having very similar but different functioning Tokens. I imagine the Fiscal department over in Irvine would prefer getting WoW Tokens out of players’ bags via Account Services rather than needing to defer possible months’ worth of subscriptions anyway.

So, we’ll see how it shakes out.
