The dGPU is certainly in Apple’s cost, but it’s not currently reflected in the price. I don’t expect the 14” to change much with respect to pricing, though at least the $1,799 model will probably increase to 512GB base, which effectively is a $200 price cut. It’ll probably still be WiFi 5.
Honestly, I would rather them start at 16GB RAM than 512GB storage. You can always expand storage but not RAM.
