Inside sources have told Airlock Alpha that NBC execs have asked “Heroes” producers to wind the series down; a season finale possible as soon as May.

NBC has denied the rumors.

“Heroes” might not be the only one saying good-bye this season. With NBC looking for a firm finish in fourth place among all the networks once again, the new guard coming in is looking to really change things up, including possibly a completely revamped lineup that could include the reduction of hours devoted to “Jay Leno.”

Hold on to your butts.
