NBC will very likely cancel "Heroes," reports former TVWeek TV Editor Joe Adalian at New York Magazine's Vulture website.

There had been reports that NBC was contemplating one last go-round for the series -- a fifth season of 13 episodes to close out the show -- but now that is not as likely.

The word from agency sources and industry experts is that more "Heroes" would simply be throwing good money after bad.

i think they should do a shorter run "mini-series" of maybe 6 to 10 episodes, if they get a good story/plot run, find a good slot for it and promote it right it could work and tie up the loose ends.

they spent to much time the last two seasons going in circles and lost all their audience in the process.

I hope they tie up the loose ends. It's still a good show--just not as good as the first season was. My favorite character is Hiro; time travel just seems like a cool power.
