having a 4 year cycle would split fanbase much more. Every game work fine on the base console, actually the pro was most of a left over since they made sure all games worked on base most of the games on Pro was just little more pixels and stable framerate.

Well the original Xbox had a 4 year cycle and the 360 did well. Same with the WiiU to Switch.

Im more inclined to buy a new console for 500, than an upgrade of the current one for 400. 

There's an obvious reason both of those consoles released a successor very quickly.

Xbox- 24 million

Wii U- 13.56 million

If you're the market leader like The PS4 cutting out over 40 million unit sales after the 4 year mark and billions in profit would be madness.

On the software side longer generations allows for multiple releases from studios, familiarity with the hardware, advancement in tech and hopefully better games.
