As with Dawnguard, the DLC is a timed exclusive release for the Xbox 360. PC and PS3 releases will follow later.

Is there ANY news about how this one will function on the PS3, or will it also be unsatisfactory?
And if you don't know, find someone who does.
Honestly though, I'm glad this is the 2nd DLC that MS bought exclusivity for, because now there won't be any excuses left for Bethesda on the next one other than "sorry, we're not smart enough to code for the PS3 even though many game companies figured out how to put large scope games like skyrim with terrific graphics and no lag and few bugs."
