First of all, sony isn't exclusive king, not even close to, half of the games you listed are 3rd parties and if we made a list to compare the number of ips sony have vs nintendo, nintendo would pretty much triple it, not even talking about sales where nintendo first parties are way more successful.
Second, you and some people here are completely delusional and really need to study a bit about mobile chips before making posts like this, you know why? it's IMPOSSIBLE to have a handheld with ps4's power, i'm sorry to destroy your dreams but the switch isn't outdated as a handheld (it is for home console) and you can't have anything much better than it, even with an unlimited budget, there's not even technology enough to build a tablet with the switch's size and xbox one power yet, ps4 is even more crazy to ask, even the damn parker chip is wayyyyyy far from reaching 2 teraflops and it's nowhere close to ps4 memory bandwidth, and we are not even talking about battery, there's NO advance in battery technology and even if we HAD a mobile chip under 7nm as powerful as the ps4 it wouldn't run for more than a few minutes before running out of battery.
