Okay... I wasn't sure if this account would be different from an account with beta. I would feel bad if this account had no achievements at the games release, while another account of mine that I never play on had once-in-a-lifetime achievements from the beta.
Gears Of War 3 gave people flaming weapon skins and a badge in their beta and let only the beta testers keep them at the official release. Nobody but the beta testers ever had these skins or badges again but the beta testers. This was really unfair for all of the customers.
Glad Diablo 3 won't be doing this. Beta tester or not, you will be equal then :P
