I don't think it matters for the Pro market segment, they are folks willing to spend extra on a top-end phone year over year - sure the media are going to milk this, but sales are probably not going to suffer much this time around.
The Pro and eventually the Ultra (if it exists/comes out) are premium models, it's going to be an entirely different story next year when they jack the price of the regular iPhone, tho.
Apple has already confirmed that prices for iPhones, iPads, and Macs will increase due to the DRAM crisis. According to the latest information from Bloomberg reporter Mark Gurman, these price increases are expected very soon.
