Probably not much. At least advancements wont be like the difference between going from 1.5 mbps to 1 gbps. It's the same reason why 10gbe ethernet has not become a common thing for consumer level desktop hardware. While 1gbe ethernet has been the standard offering since the mid-2000s. Recently lot of manufacturers have started supporting 2.5gbe. But low cost switching/routing hardware that fully supports 2.5gbe isn't quite there yet.
