Right now the wings are not in the best spot for a new area with the current economic times. Unless Mr. Illitch would want to pay for the arena out of his own pocket and we know that will not happen (amazing that the late Pistons owner Bill Davidson did that, you dont ever see that)
Plus with arena needing sponserships and suites for businesses it would not be happening with all that is going on in the state right now. Everyone who has been there knows the arena was not built in the best way (real steep steps climbing to your seats, bad sight lines, and also the press box was "Forgot" and not built in untill after the area was completed) I think they will work on a short term lease and cross there fingers that the state is in somewhat better shape in a few more years
