HD DVD and Blu-ray delayed again, as AACS is pushed back
 

Remember all of the positioning about which next-generation optical format would hit the market first? Forget about it. It now appears that both formats will hit the market at the same time, because delays in the security specification that they both share have left everyone—device manufacturers, movie studios, and the leaders of the respective formats—in a holding pattern. The final specification of the Advanced Access Content System (AACS) has been delayed again, meaning that the final specifications needed to produce HD DVD and Blu-ray products still sits off in the undetermined future.
