It will peak next year. Nintendo will be the first to upgrade in 2017 (if the Fusion idea is the way they'll go, both Handheld and Home console wil release at nearly the same time). Microsoft will follow in 2018 if they decide to make a new console. I expect the PS4 to sell well into 2018, so they might wait for 2019 to upgrade so the can get the best hardware.
