Will the next Freerunner revision have a proper mini USB-AB receptacle
like the one at
http://www.cypressindustries.com/mini_usb_ab_connector.html ?

The spec sheet is at http://www.cypressindustries.com/pdf/CCMUSBAB-32005-700.pdf
I found the connector via http://www.cypressindustries.com/products/usb.html

Also, where can I find the spec sheet for the receptacle currently on
the Freerunner? I'd like to solder on my own. Any thoughts?
