All i see is just natural progression of technology for both consoles, and handheld. I don't get the analogy. portable tech was impressive with psp, and vita, and switch is just a evolution of that.
Hey, I was impressed by those portable consoles, too! I personally feel like graphics were "good enough" when we reached PS3/X360 levels. After that, it was just fine tuning and performance. You can see the improvements being made today but somewhere in that area, the "wow factor" just went away for me.
Vita was pretty powerful but it wasn't quite there. I was definitely impressed by it but it was still below 7th gen home consoles based on the titles I bought. With the Switch, portable gaming had hit that "good enough" area. I guess that means I probably won't be as impressed with future portable systems, either. I'll appreciate the improvements but my mind won't be blown like it was the first time I played Zelda BotW.
VR is going to have to carry the load until it reaches a point of diminishing returns, too.
