XBOX Music MP3 Player

Is Microsoft coming out with an XBOX MP3 music player to replace the ZUNE? With the unveiling of the new XBOX music service it would make sense to make an MP3 music player (hopefully multiple versions similar to IPODS). I realize I could listen to the XBOX music service on my phone or tablet, however, I do not want to waste my phone battery and would use a dedicated MP3 player while working out or commuting to work.

Thoughts?
