"Heroes," produced by Universal Media Studios, has struggled in the ratings its third season. It’s understood that Alexander and Loeb were let go because of the frustration by NBC’s executives with the creative direction of the show.

It is also said that "Heroes" has been grappling with hefty budget overruns this season, that are going well beyond its already sizable $4 million per-episode pricetag.

So the question is how much longer do you think "Heroes" will last?
