Where is Bob Dylan Going From Here?

I just checked the official Bob Dylan page and Bill Pagel's Tour Guide and noted that there are no concerts scheduled for the Never Ending Tour.  What could that mean?

1. The Tour is finally over as Dylan is 78 years old and needs to retire.  Has the joy of touring ended after all these years and he is retiring from touring.  Other artists made announcements when their touring days are drawing to an end, but Dylan, of course, is very uncommunicative.
2. He is going into the studio for a new album.  Tempest in 2012 was his last album with his original compositions.  He can be very unpredictable.  Since a Bootleg Series boxed set was just released, I doubt if another one is coming soon.

We shall see what we shall see.
