I'd assume that the webseries is canon and the comic is semi-canon. I also think we should consider them like so until they actually come out, when we will know for near-certain. I think we should include them all on the wiki, although for the comic (as said before) we can only post the cover for copyright reasons. The webisodes could be treated the same way as regular episodes (that is how they do it on the Walking Dead wiki).
