From id CEO Todd Hollenshead’s .plan file:

“So, the next question is release dates. Retailers in the States will be allowed to pick up games starting at 12:01 AM on August 3rd. The official street date is actually August 5th in the U.S.A., but some of your favorite stores will probably have it early for those of you who have to have it first. Check with your local retailer for that information.”
