It is true that Fido itself always uses biometric as an example. The casual finger print sensors on all phones and laptops will probebly be the most widly deployed authenticator. Biometric authentication companies are part of the support base for the Fido Alliance and they always push Biometric into the front as well. There seems to be no company that is about to release a pin or password hardware authenticator that could advocate for the alternative. Also the press loves the hole 'remove passwords' storyline.
