Most people will tell you they don't view phones as a luxury item. They need them for work, contacting people, so on. You can make them iterative because they break, get lost, and people like shiny new upgrades for stuff they have to have anyway.
Consoles are not phones. They do a ton of stuff, but you don't "need" them. You buy it as a luxury item and expect it to last 5-7 years. The only people that don't are people who've become overly tech conscious, and they don't make up a large enough number for Sony to change how they do things entirely.
A new iteration doesn't break software support, just look at PS4 Pro and Xbox One X - oh, and smartphones!
