Bethesda has told Eurogamer that "finishing touches" are being made to Operation: Anchorage on PS3, but offered no firm release date for the Fallout 3 content. We had been prepared for a late June launch.
Speaking exclusively to Eurogamer, chief spokesperson Pete Hines said getting the DLC (which has already been released on PC and Xbox 360) to work on PS3 takes quite a lot of effort, actually.
"Yes, quite a bit actually," he said. "It's a different platform with a different way of doing things and it requires special attention and plenty of testing before it's released."
"We are trying to put the finishing touches on it now, but as I said above it's a different task than DLC on another platform, and so there are things we have to finish doing and testing before it's done on PS3."
Testing being the operative word; Operation: Anchorage, The Pitt and Broken Steel all arrived on Xbox 360 amid technical problems. Point Lookout, on the other hand, arrived this week without incident.
The fith and final piece of Fallout 3 downloadable content will be Mothership Zeta, which is pencilled for late July.
"Haven't set a final date yet," said Hines, "[but] should have one before too long."
"What's in store? Alien abduction done really, really well. What more do you need to know?"
Bethesda reckons the other Fallout 3 add-ons will follow Operation: Anchorage in intervals of around a month to six weeks. They will cost a similar amount to the PC and Xbox 360 versions, which charge 800 Microsoft Points (GBP 6.80 / EUR 9.60).
You can buy a combined pack of Operation: Anchorage and The Pitt in shops for 15 quid, too. A Broken Steel and Point Lookout bundle will follow in August.
Or you can wait until October for the Game of the Year Edition, which contains all five add-ons plus the original Fallout 3 game. This will cost GBP 40.
By then, however, fans with all extra content plus the original game will have spent GBP 74. Is it fair to expect dedicated fans to spend so much?
"I think, given all of the content and gameplay, it's a good match of dollars to your hard-earned money. I can point to plenty of games that don't give you nearly as many hours of gameplay, or fun, for GBP 34," said Hines.
And, for what it's worth, Hines agrees that playing Broken Steel first makes most sense.
