Figured this could use it's own thread. Based on this thread on the beta forum http://forum.worldof...555#entry665555WoWs is going to the now very common open beta as soft launch model.
If you buy a pre-order bundle you'll get tokens (the CBT premium currency) equal to the amount in the bundle to use during the CBT. Then when the game goes into open beta the cbt stuff will be wiped and you'll get your full amount of doubloons added to your account.
One change from previous open betas that I have mixed feelings about is that there won't be a wipe between Open Beta and Launch. So the gold you spend in Open Beta will be spent and you'll keep your progress. While not having to regrind trees at launch will be nice, I've always liked that WG didn't start charging for real until the game launched. Also it doesn't seem like there will be any account linkage during CBT or Open Beta so the gold you buy will only be spendable on WoWs and your xp and premium time will only be on WoWs.
