Whose to say he's coming back to earth, with Metatron running Heaven, it might help to have an agent working agaist him up there.

Having said that I would love so see him come back again. I would also love it if the episode where he returns starts with him in heaven in a recreation of his house just reading, while his wife makes him dinner. Theres a knock at the door, suspicious he grabs an angel blade  from his desk (if anyone can swipe one its him,) and opens the door, there a reaper is standing who says "mr singer I'm afraid were going to have to ask you to come out of retirement, the world needs you again." Bobby pauses, rolls his eyes and says "I'll get my coat," before turning and calling to his wife "Honey, it looks like I'm going to be late for dinner, somethings come up."

Just an idea I had.
