It has been http://www.bethblog.com/2012/08/02/dawnguard-ps3-update/ that the PS3 version will be delayed a bit as they are still working to ensure acceptable performance on the platform.

Earlier in the month, we provided an update on Dawnguard's status for PS3.

It's been a few weeks, and we wanted to make sure everyone knows where we're at with Dawnguard. Skyrim is a massive and dynamic game that requires a lot of resources, and things get much more complex when you're talking about sizable content like Dawnguard. We have tried a number of things, but none of them solve the issue enough to make Dawnguard good for everyone. The PS3 is a powerful system, and we're http://www.gamesas.com/topic/1413248-ps3-release-for-dawnguard-thread-23/# to deliver the content you guys want. Dawnguard is obviously not the only DLC we’ve been working on either, so the issues of adding content get even more complicated. This is not a problem we’re positive we can solve, but we are working together with Sony to try to bring you this content.

We wish we had a more definitive answer right now. We understand the frustration when the same content is not available on all platforms. When we have an update, we will certainly let you know. We deeply appreciate all the time and support you have given us, and we’ll keep doing our best to return that.

"Yes, it’s just doesn’t perform well in all scenarios. Some folks would be fine, some would not.”

One of Bethesda’s top PR execs, Pete Hines, (who holds the position of VP of PR and marketing), tweeted to a question that concerned the release date, saying, “No, we will not release it if we can’t get the performance to an ‘acceptable’ standard. Our stance on this has not changed.”

We haven’t given up. We’re still working to see what’s possible.

Our team is still working to make PS3 content available on PS and doing everything possible to make it a possibility.

and here we are...thread 34

so is dg hf db comming out for ps3 or not?

I feel like we should be further forward by now xD

I'm still waiting with hope.

Atlest you still waiting with hope....all my hope died.....then was reborn and then killed again.

Don't you mean slowly disintegrated from the feet up and once it reached the hips they re-grafted new legs and began the process anew?

Nope...just dead with no chance of ever haveing it be reborn this time around.

Could be worse, they coulda released this for the Wii XD

....a part of me would like to see how that'll play out and an other part of me is like I hope to god they never do

You know there'd be problems due to the fact that system is so badly outdated it's not even funny.

XD yeah true, I play mine for the classic stuff, Legend of zelda OCT, Super smash brothers and that's about it.....OH Monster Hunter Tri

Playing Megaman Zero X5 on mine XD it's good to own all this gens consoles

yep, well...I own a PS3 and a PC, the Wii is my Parents, my little sister has a PS3 and my Sister has a 360

You guys should call Guiness and be like "I think we've got the world record for most threads opened pertaining to an unreleased DLC for a video game."

These threads probably serve no purpose but to vent out our frustration.

For that, I approve.

If there's any actual worthwhile news, I'm sure it'd pop up somewhere else in the forum as an update from Gstaff.
