It looks like PS3 owners 
are going to have to wait a while longer for the formerly exclusive DLC for 
Fallout 3 to be released on their system as it's taking Bethesda a little longer to port the content over.  The good news is that they'll be releasing the Broken Steel content first which should make fans happy as it's one of the better ones Bethesda has released (John 
really liked it).  Given Bethesda's rather spotty history with bugs in the 
Fallout 3 DLC this is probably a good albeit frustrating thing for PS3 fans.
