I don't think anything will happen, although people can write their own "plugins". It's already a speaker/microphone, why not make it a speakerphone; if you slipped and broke something and can't even crawl to the phone, saying "Alexa, call an ambulance!" and being able to communicate with the rescuers would be helpful. Sadly it's not in their spec to be used as that, yay for closed hardware!
Alternatively, Amazon should have a log of music you asked it to play. The suspect is named Bates. If you were being chased by him, could you yell "Alexa, play music by The Police!" followed with "Alexa, play the soundtrack of Bates Motel!"? You'd be dead but at least there'll be a hint for the police somewhere in the cloud.
"Alexa, play James Blunt!"
"Alexa, play Bates Motel!"
"Alexa, play The Killing Hand by Dream Theater!"
