As I understand it, using this node size has some high setup costs. It was one reason the Pi Foundation was stating that any major changes in the Pi would require a node change which they couldn't afford themselves.
Also supply of 7/10nm fabs is not a commodity. GloFlo won't even invest in it and is staying >20nm for now. That leaves Samsung, Intel and TSMC.
Until fab equipment for those nodes become near commodity, you probably won't see anything like that from Rockchip.
