The latest series of branch routers from Cisco, the ISR G2, includes both a traditional serial and new-fangled USB console port. Essentially it's just moving the USB-to-Serial chip inside the router, but it does eliminate one potential thing you can lose or forget. They're going to be including both option on several new devices in the future but it's going to take a really really long time for serial to completely go away.
