I don't think it is a chicken and egg problem. There are several of CPUs that support > 16 lanes, so a high-end GPU (paired with a high end CPU) could use more lanes if it needed it.
Currently it seems 8 lanes of PCIe 3.0 is not quite enough, but 16 lanes is plenty. So we'll need a few years to get up to utilizing 16 lanes completely.
At which point 4.0 may be ready.
