Doubt it. Seeing as it's still part of NS:1, it's not going away anytime soon on current wikis, not sure about newly created ones though. And I'm also sure that they wouldn't take the time to move several hundred thousand (if not more) talk pages to some #WikiaArticleComments. It's not like they are adding a "Foo:" namespace where you already have "Foo:" and it'll be unrecoverable after installation/addition to the LocalSettings.php.
