I'm always amused when people talk about Jon going back to his roots and then cite album like SWW, NJ or KTF. Those albums were the path that lead them to glory, but Jon never had been a hard rocker to begin with. His roots are down the Jersey shore, bar band stuff like Springsteen or Southside Johnny. Listen to the Powerstation recordings or at what material he selected for the KOS shows in the past and you get an idea of the kind of music he wants to play.
