Introduced to this thread by Tacopill up there!
Anyway, as far as I know the users there aren't very eager to move at all. The community's not actually that active, and I haven't found anything regarding Wikia or moving. Otherwise I don't have much to say, but I don't support it because at the NIWA wiki we've already established our own "customs" and stuff.
Not to mention the fact that their articles aren't really that well-kept.
