If you're torn between keeping your existing beta characters or rolling anew as an Asura or Sylvari, ArenaNet has made your choice a great deal easier. All existing beta information (characters, items, and likely server selection) will be deleted. You'll keep your contact list, but that's about it! This wipe will happen both before and after the upcoming beta weekend, so you'll have a clean slate for the last test and then again for the headstart weekend or launch proper. In addition, transactions in the in-game gem store will require actual credit card or PayPal purchases. While items bought in the store this weekend will be wiped, a record will be kept of how many gems were purchased, and those gems will be waiting for you after Guild Wars 2 launches.
