You'd have to harass w3bz (i'd suggest PMing him) for a real answer, but when I set up the wiki I intentionally left the copyright information blank, simply to get the site up rather than wait for Rebellions legal to work out what they wanted.
I'm not sure in which direction it would go, seeing as a lot of works posted on the wiki, like covers or even snippets from the issues, may feel under one legal umbrella, while a great deal of other information and writeups about issues and stories probably belong under CC or other general use lisences.
As far as Rebellion are concerned I don't think they're interested in laying claim to anything you write on the Wiki, such as information you post there, they just want to ensure they keep ownership of works that belong directly to them, like art or story extracts.
Again, badget w3bz for an answer, I don't think he reads these forums too often, so try PMing him or Wake who should be able to get in contact with him for more info. Hope that helps.
