I was thinking wether or not we will be getting Skyrim's DLC so I looked at what Bethesda said which is - “We would like for everyone to have a chance to play Dawnguard, but we aren’t going to release it for PS3 knowing that some people’s experience in Skyrim will be worse. We do everything we can to have our content available to all; from our free updates, to user mods, to paid DLC. We’re as disappointed as our fans when that isn’t the case, but we’ll continue to push for that reality.”
This sounds abit off because Bethesda hasn't in thier past shown any care about performance towards the PS3 or its users and could be just a set up and they havn't really even started production for the DLC on the PS3, another GStaff has been very active on the PS3 forums (well not as active as everyone would want him to be but more than he normaly is) which I think just add more to the set up that Bethesda is starting to care more about the PS3 and its users. Lastly patch 1.6/1.7 was meant to have dawngurad trophies this just add more that Bethesda most likely from the begining planed not to give the DLC to PS3.
Now because I know there are alot who will still want to buy the DLC don't worry because I can be wrong mianly because you never know Bethesda has (in some one or other) started to care more about the proformace of the DLC on the PS3 and its users game experance and GStaff has been more active because of this. The trophies not in the patch could be that bethesda plan to realese a patch that brings them in sometine in the future and didn't put them in the patch that they were meant to because they know that DLC it going to take longer than expected to fix.
So thier's my theroy if you see a flaw please say and i'll edited/update the post.
Thanks for reading.
