I haven't seen pics, but I hope to holy hell USB3 cables have better connectors.
While I agree with your sentiment, changing the USB connector is pretty much out of the question.. That would suck ass.
I am sure USB will eventually be replaced, but it still has a long time to go if we look at how long the serial (DB9) connector lasted.
I suppose they could theoretically change the connector, but still have backwards compatibility. I would be okay with that.
