You still mising point, 95% of PS4/XB1 game have same price point, and 3rd party would need to have higher price for games that have better performance on PS4 Pro and Xbox X compared to PS4/XboxS buy your point. Vita doensnt fit in comparision beacuse Vita same like 3DS offers only handheld expariance, that isnt case with Switch.
I just gave you an example of a home console game on a handheld (Vita/VitaTV). Believe me I see your point, but at the end of the day just because a PC, xb1 or a ps4 game is on the Switch or any handheld for that matter, doesn't make that game on par.
Oh and before you say "well PC games should cost more!" No they shouldn't because not every PC is the same.
Vita/Vita TV are two products not one like Switch, and Switch games in docked mode working at higher resolution compared to portable mode. Do you understand difrence? Vita is just handheld, Vita TV is devaice that lets you play some of Vita (handheld) games on TV, and you need to buy two difrent devaices. Switch is a hybrid, has full home console AAA games that can be played in full handheld mode or in full home console mode.
OK about PC, but than games for PS4 Pro and Xbox X would need to cost more compared to PS4 and Xbox S, buy your failed logic.
