Absolutely nothing of consequence.
That's too bad. I have to admit, the optimistic part of me was kind of hoping for a recall/re-release of Skyrim coded to work properly on the PS3 console. However, after I thought about it, the optimistic side of me was beaten into submission by my memories of past games and the lack of regard or concern Bethesda has shown the PS3 community.
The extreme silence is disconcerting though. Gstaff completely ignoring PS3 users on the blog, not even mentioning the "we're working on it" line. Pete Hines and gstaff's twitter feeds going quiet about their latest release. That is very weird. One would think they would be gushing about the new, shiny DLC they just announced, but no. Nothing.
