On Friday Blizzard confirmed that it will offer a “Starter Edition” at launch — which is tomorrow, May 15 (or tonight at midnight). Unfortunately, it won't be open to the public from the start, but instead be limited to Guest Pass keys that are provided with the paid boxed copy. Naturally the only way to gain one of these keys is to nag a paying customer, or wait until Starter Edition becomes available for everyone thirty days from tomorrow.
