Breaking News: You're about 7 hours too late. We'd already figured this out 60 minutes after the update was released. I was one that started this thread and I, thanks to my fast internet connection downloading 24gb in about 25-30 minutes, appeared to be the first one (on here at least) that had it up and running (offline mode before the servers came back online). Even in offline mode it was clear there was no new content.
Although it appears I owe PD an apology (not that they'll ever see this); it wasn't a messy patched codebase that I suspected to necessitate a full reinstall of all the updates but a bug in Sony's update network/servers. So, umm, sorry PD.
