seems like a total improvement.... swapping 1 well known, simple cable for 2...

hurray progress?

The USB port is probably cheaper than anything else. And it gives them more flexibility.  No need for both an RS232 and 
Ethernet console port.
The USB port can be both, depending only on driver/application support on the router.  And you have other options as 
well. Wifi console maybe?
Or a direct USB-USB cable (with the necessary logic to appear as a device to both ends).

It is also possible to create USB only console servers, if the market wants that.  Avoiding two RS232 conversions per 
console port will save enough capacitors to run a Tesla.

Whether these alternatives become available is of course up to Cisco.
You do need the driver and application support on the router.  Time will show what they come up with.
