I don't believe they will ever be phased out together, but I do think the retirement age will continue to rise. In a way it makes sense as people are living longer and staying healthier for longer too. When I was six my grandmothers were both 65 and seemed like old women. Now my aunt is getting near to 65 and doesn't seem old at all. (And yes, I know that's partly my personal perception changing as I get older, but I think in general 65 no longer seems old.)
