I can't seem to find anything about a PS3 release date, but I did find a thing on GameFAQ where people were complaining that this was an Xbox exclusive update. I kinda doubt it since it is available for the PC as a beta.
Here is a list of the supposed fixes:
there is no information about releasing to PS3 at this time.
many have asked on the Bethesda forum and all get either no response or just 'we have no information at this time'
I can't believe how those guys have treated the PS3 community and it seems to just keep getting worse.
