I believe Kaby Lake G was planned to show that integrations to GPU with CPU on discrete level can be done in mobile, but EMiB was the just the start Foveres was the next step . EMiB is also use for PLA logics which they got when they got Alteres
So what the next stage of process - likely Gen12 with 11th Generation version of CPU. or possibly 6 or 8 core version of IceLake. I hope that it actually a 8 core or higher version 11 th generation with mobile Xe.
