Looking at the above, it is clear that Intel is killing Iris Pro Graphics (GT4e). Looking at the H Processor (currently used in the MacBook Pro Retina 15"), it is clear that both Kaby Lake and Coffee Lake will only be available with HD Graphics (GT2). This is mostly likely because Intel is seeing very low demands. There are very few PC manufacturers that buy H Processors with Iris Pro (aside from Apple). Unless Apple is willing to release new MacBook Pro with graphics inferior to its predecessor, Apple is going to have to release MacBook Pro Retina 15" with AMD (Zen based) processors or it must ship all rMBP 15" with a discrete GPU (dGPU). This charge does not affect the MacBook Pro Retina 13". Looking at the U Processor (currently used in the MacBook Pro Retina 13"), it can be seen that Kaby Lake and Coffee Lake will be available with Iris Graphics (GT3e).
