Why would they bother with all the Intel GPU work they have been doing? Whatever "that one" hardware configuration would be, it wouldn't include an Intel GPU...
Without any real knowledge of the industry, extrapolation to back up my point seems fraught with error. How much of Intel's progress has been the low hanging fruit, and is that last 10% going to take 90% of the time? And what measures would you actually use to measure progress?
I think even Intel would have a hard time producing something not just comparable to Nvidia/AMD's offerings today, but future-proof as well. Their stuff has gotten a lot better recently so I don't think there is any lack of effort on their part, there is just too much catching up to be done.
