If cost/transistor continues to not improve, industry-wide, it spells the end of Moore's Law, at least for mainstream applications where cost is a primary factor.

However... where size itself (and power consumption) are the primary factors, there will be demand. Which means that SoC GPUs will adopt new process nodes more vigorously than video card GPUs. http://www.embedded.com/electronics-news/4304118/Imagination... Sounds like disruption.
