Just wait until phones and tablets move to MicroUSB 3.0 and we have two different MicroUSB standards to deal with during the transitional phase.
That's more or less how it'll look. While it'll allow much greater data transfer rates, by the time it's fully adopted in mobile devices it's more than likely we'll be relying almost entirely on wireless transfers and cloud-based synchronization. Perhaps not for transferring a full local music library (which is where this would provide the most benefit), so the logic stands, but I digress. I have the One as well as both generations of Nexus 7, so at this point I'm used to it being flipped for some devices.
Edit: also the two posts above me.
