Most of the Arduino Nano clones on the market have already been substantially or completely redesigned. It's a pretty trivial board, in all honesty; given the desired pinout and dimensions, a skilled designer could probably turn out a Nano clone in a day or so. The Arduino Pro board in question here is substantially more complicated, but I wouldn't call it particularly innovative either.
