It takes about a generation for Phones to start getting near a console... At the moment we are in that funny place of having games with Xbox 360 levels of geometric complexity but with some other assets reminiscent of the Xbox One/Playstation 4.
Yeah that's how high-end handhelds vs consoles have been for the last 30 or so years.
Game Gear released around the time Genesis/SNES did but was on par with Master System/NES.
Sega Nomad released around the time PS1/Saturn/N64 did but was just a handheld Genesis.
PSP released 1-2 years before 360/PS3 but was a bit under DC/PS2.
Vita released 2 years before PS4/XBO but was under 360/PS3.
Switch released about halfway into PS4/XBO generation and is right in between 360/PS3 & PS4/XBO.
It seems like high end portable hardware is always like 7-8 years behind home consoles.
When the herd loses its way, the shepard must kill the bull that leads them astray.
