Sony WS-Series to come with a remote?

I stumbled upon a certification from a Russian website for the new WS-Series and it seems there might be a remote for the new Walkman.

The same remote was certified on e-POSTEL at the same time as the NWZ-WS615.  Same situation on the FCC, both the remote and Walkman appeared on the site on the same day.  More photos after the break.

While this is only an assumption, my best guess is the remote will be used to control the WS-Series via Bluetooth, but there is no real evidence apart from the Russian website stating "with remote control...".  This should also come at IFA, along with the WS-Series.
