Last week, there was also mention that the C&D didn't ask them to remove all information, only "over-the-line" info, such as screenshots or video. But apparently that clause doesn't apply to the new host -- there are still screenshots all over the site, and though Vivendi has pulled video from YouTube before, it's still there as well.
Of course, any C&D sent to the old site would still apply to the new one -- it's just a question now of whether the wiki's new host will comply with Vivendi's demands (the wiki's creators sound very sure that they won't). And after that, it'll be up to Vivendi to determine how far they want to take this -- if they really feel that having this leaked information on that site has hurt them in a justifable way, there is a possibility that an actual lawsuit could be issued, and if this escalates even further, the two parties could eventually end up in court. As always, we'll be watching to see what happenes.
