Capcom’s revealed that the DLC included with its Gold Edition of Resident Evil 5 was originally to be included with the game when it was released last March.
Producer Yasuhiro Anpo confirmed on his blog that both Lost in Nightmares and Desperate Escape could have appeared as an in-game extra.
The reason for the omission was due to the production budget. In fact, instead of using live scenes with the game, Capcom considered using comic style cut-scenes, but in the end decided against it.
Instead, proper cinematics are being used for both pieces of DLC.
The Gold Edition of RE5 releases on March 9 for PS3 and 360 in the US.
As for when the announced DLC will see release on PSN and Live separately, find more info here.
