For my wife's sake I hope they keep around a smaller device forever. When the iPhone 5 stops getting updates then she will need to find something else. It would be nice if Apple kept around a smaller, cheaper, lower-spec'd device for people who don't really care about performance and just want an iPhone that fits them. I'm thinking iOS 9 will drop support for the 4S, and iOS 10 will drop support for the 5, so I should be able to find a 5S for pretty cheap in 2016 to keep her going until iOS 11. Hopefully by late 2017 there are still some small iPhones available for sale! And yes I've tried to reason with her but she insists she can't get a bigger phone. She was already mad when they went to 4" lol.
