The wikis aren't technically leaving, they're forking: they create a copy of the content elsewhere. The previous content will remain on Wikia, attracting google hits and pageview and possibly new editors for the ones who moved. The impact will be felt more long-term, when there won't be good editors for then-current franchises who choose to commit to Wikia.
