Word is going around that Intel may have cancelled its Iris Pro graphics. So far, Intel hasn't announced any 7th generation Core processors with Iris Pro graphics and a recent leak reported by Notebook Check.net confirms there are no CPUs with Iris Pro on Intel's 7th gen roadmap.
FUD Zilla points to speculation that Coffee Lake, Intel's next generation, may not have Iris Pro graphics either. We'll probably learn more over the coming months but given what we know at the moment, things aren't looking too good for Iris Pro. We're not sure what happened, but perhaps Intel decided it's not worth it to dedicate its resources to a product that competes with low-end discrete video cards.
So beginning with Kaby Lake and continuing with Coffee Lake, it would appear that only GT2 graphics, which Intel brands "Intel HD Graphics," will be an option. So basically Intel is keeping Iris but just not the Pro version. What appears to have happened is that Intel has worked out that Pro is competing with standalone GPUs. It is handy in power and space-limited systems but really those sorts of systems are not going to want heavy duty integrated graphics.
