IMHO, if not for bug fixing, I doubt that Dell would spend time to tackle this "USB and power at the same time" improvement on the DV8P. What Dell will do instead is to release another model a few months later with such feature support. And maybe add on USB3.0 connector as well since the motherboard already supports it. The effort is minimum since they just need to fine tune the side case design in order to fit in the USB 3.0 port. Marketing strategy.
