It will depend greatly on how Facebook actually does this "deep integration" the article mentions. If they are just going to plug into skype and let your FB info become your skype username and pw, then adoption might not take off as much due to having to open and run a separate application to do anything. On the other hand, if they make each facebook chat a virtual skype call and incorporate skype sessions onto the backend, then I could see this improving chat and make adding video capabilities fairly easy. As for it taking off, if it requires no extra work then sure, their userbase might grab it and go. If it's just a plugin for skype the application, then I'm not so sure.
