Why should people opt for a mini version when they can't get the best experience on the original Switch? The potential of a such a model would be limited by default.
You do realise you dont make any sense again!? Buy your point Pro and X would need to be best selling option of PS4/XB1 because they offer best experience for PS4/XB1. Low price option has much higher potential for sales than higher price option, with lower price option Switch will be much more popular among kids, families and casuals that actualy one of most impoartant part of market. There is reason why Nintendo released very low price option for 3DS in form of 2DS, 2DS is selling very well.
