Im not sure how the handheld crowd will react to 2.5 hours - 3hours of battery life, in a game like Zelda BoTW on the Switch. Nor the 299$ price point (very few handhelds are sold that expensive and sell well).
The handheld crowd that buys nintendo handhelds is a huge part of their market. Hopefully once nintendo cuts price by like 100$ the 3DS owners will start jumping ship to the switch.
