The good news is that the new USB plug will be reversible so you won't have to fiddle around with it like you do today. The bad news is that the new USB won't be compatible with existing connectors.
Cue up the extra ports and time to phase out existing hardware.
According to the USB 3.0 Promoter Group, an organization that proposes standards and thinks about things like USB ports, work on USB 3.1 has begun.
