I bought the Collectors Edition back in October 2011. It was a digital download, not the boxed version so I didn't get the manuals it mentioned, etc. As for those skins....same as you I can't seem to find them yet.
I also have a copy of the Gold Edition I recieved as a gift. Maybe I'll try two installs, one of each, and see if there are any differences or they're the same just named differently.
