He's just another old hard-liner. No real reform is coming from him. With his age I don't believe it will be that long before we see yet another new pope.
While what you said is certainly a possibility, I'm not so sure the the age factor automatically means a short wait until the election of the next Pope. As I stated in another thread, the longest-lived Pope in history (that we know of with absolute chronological certainty) was Leo XIII (served 1878-1903) and he survived and governed the church until his mid-nineties after spending a little more than a quarter of a century on the Papal throne, the third-longest reign for an elected Pontiff.
Francis may be 76 and have just one functioning lung, but with access to modern medicine and much longer life expectancies for most human beings in general anything is possible. While I'd never count on it, Francis could be Pope for a lot longer than many observers think.
