yeah or maybe microsoft have paid them out
Really?
That is completely ignorant.
Learn of Sony's architecture before making baseless accusations.
In the first months of Skyrim's launch on the PS3, the game was laggy, and had extremely poor framerate. Even now, with saves that surpass 8mb the game will lag.
Dawnguard suffers from similar problems and must be recoded to fit with PS3's architecture, but now there is the problem of Skyrim not accepting this recoded Dawnguard because of the way Skyrim is coded. This problem will continue to the other DLCs until Bethesda finds a balance.
The PS3 has a divided RAM pool (256mb to GPU and 256mb to CPU) which works extremely well for 1st party games. The Xbox 360 has a shared pool of RAM (512mb shared between CPU and GPU), and that allows games to access what it needs and when it needs it.
It is getting really annoying seeing these "Boycott Bethesda because they won't take our money for DLC!" comments/replies/topics because they don't make any sense.
Bethesda Softworks is a business owned by Zenimax Media (they own many companies including id Software). With both companies being for-profit businesses, it makes NO sense of why they would cut off an easy revenue source on purpose.

Honestly, I think that PS3 won't get and DLC until a GOTY edition.
