Update 10/10/12:

We've received word from Sony that customers experiencing this issue should now have received a voucher for the All-Star Break DLC. Thank you for your patience!

Previous update:

We are aware of an issue where players who pre-ordered the direct download version of NBA 2K13 from PSN are not getting the All Star Break DLC. We are currently working with our partners at Sony to correct this issue and will update our players/customers via this article and follow-up via email with the solution.
