Interesting claim, probably quite true also. The Tegra X2 was available for the original Switch but wasn't put in, likely due to Nintendo wanting to make more money on the original console. Though I imagine it poses a problem that other companies working on handheld technology, whether it's mobile phones or tablets will inevitably create a better product. It's a pair of controllers and TV connector away from a Switch. All three of which, can be bought separately on eBay from various third party vendors, it only takes one company to create the whole package and boom, contender.
Though I have to say, there is merit there. Bare in mind the P20 Pro is an incredibly good handset.
