Report: Heroes canceled

My regret is that I won't see Milo Ventimiglia on TV anymore and he may not pop up on any show soon just like what happened to Wentworth Miller when Prison Break was canceled. But this was a long time coming. Heroes could not be saved after Season Two and then Season Three destroyed it beyond repair.

From Vulture:

For weeks, even in the face of Heroes' bottom-dwelling ratings, conventional wisdom among TV-industry insiders has been that NBC was leaning heavily toward bringing back its once-mighty superhero series for a fifth and final thirteen-episode wrap-up season. But as NBC has become more confident in its slate of new shows, all indications are that our Heroes are dead.
