What will smartwatches bring to music, and what could they bring?

If you don't know about the pebble then you probably should. Here's a little video about pebble to get the conversation going.



So, my question is, what will or rather could this mean for mobile music? As Pebble are going to publish an SDK for their smartwatch will that mean that there's a possibility that there will be a musical app that runs on your wrist. Maybe a controller?

What do you think? Are there real possibilities?
