When will the tv show heros' return?

Answer 1

Due to the WGA Writer's Strike that has not ended as of this posting (1/31/08), the date of the return of Heroes is unknown. NBC will announce the date of the show's return upon the eventual end of the Writer's Strike.

Answer 2

unfortunately Heroes will never return due to the large amount of money spent on the show. NBC was thinking about doing a wrap up movie because of the nasty cliff hanger on the season 4 fanaly but decided it was too expensive.
