Realistically the best scenario will be 5 OS update and 7 security maintainance. (5 + 2)
That would basically match Apple for the realistic life of a phone. That being said, Apple did just release a security update for the 5s.
5 years of software update I think it's really fine, the phone battery will be down at that time and you'll need to replace it, maybe trading it for another phone will be much better.
Can't argue with that, although some people prefer to change the battery instead, which is also valid.
