Update: Blizzard has responded to us and said the post in their forums was partially incorrect, adding some new information. You can find their long reply here.
If you've waited to pick up Diablo 3 for your epic speed run, you'll have to wait a little longer. The recent 1.0.3 patch implements new restrictions on digital copies of the game, such as forcing new players to play only the "Starter Edition" for the first 72 hours.
- Act I up to the Skeleton King is available
- Level 13 cap
- Matchmaking available only with other Starter Edition players
- No Auction House access (Real Money or Gold)
- Global Play is not available. Players attempting to connect to Diablo III Starter Edition in a region other than their Battle.net Account's home region will receive Error 12. See the Global Play support article for more information.
A separate support page notes that 72 hour wait for "payment verification." Given this restriction wasn't in place before, it's a mystery why the change came about so suddenly.
