They'll always have iGPUs so whether or not they stay in the dGPU market depends mostly on whether or not people buy them. So they might not, whole market seems to be moving to SoCs/APUs/whatever you want to call them.

Not only will they always have iGPUs, but also cannot give up on advancing their datacenter AI GPUs (the next being Jaguar Shores). They need both of those far more than consumer or prosumer dGPUs, but that means they are committed to Big GPU work and Small GPU work.

Since they will have both of those big and small "bookends" of GPU architectures, it is a question of whether they see benefits in maintaining an accessible foothold in the midmarket ecosystem. I could make an argument for both sides of that, but obviously the decision is not up to me.
