To me, USB charging is one of those "amateur" things - like On-Board Flash - that Pentax may or may not ever provide in the future ..... but you can provide the equivalent for yourself right now; all you need is a spare battery {which you should have already} and a {cheap} charger from a company like Kastar.
And if you're me, you'll add a 30 dollar solar panel to it, so you can recharge in the bush.
But I seriously would like USB charging for longer trips for my K-1 and K-3. We are doing 16 days out of cell phone range and off grid this August. Some one come up with away for my to recharge my K-1 and K-3 batteries. As for the charger above, I have a kit like that, and have recharged away from civilization many times, but, I don't use AA batteries anymore. Those were back when I was shooting a K100D.
