When Nintendo was running the industry there were an abundance smaller IP's that could fit into a 5 year cycle because it took a shorter period of time to make the games. Today, its totally different. Sony's 10 year plan was made for their profitability. They take great risks making consoles as they do. I don't know if they knew this or not but with the costs of making games these days and the time it takes to make games, the process had to change. Sony's plan has actually proven to be more cost effective for gamers since they dont have to buy a new iteration every five years. They can just enjoy the same console for a prolonged ten years (seven years until its replaced though).
