Why would people boo when the new "Pro" models have the same pricing as previous non-"Pro" models? That doesn't make sense. If anything, the "Pro" designation would be expected to cost more.
Of course, it's going to be very obvious to most people that the new iPhone 11 is the direct successor to the XR, and the iPhone Pros are the direct successors to the X, XS, and XS Max.
