In their own words they explain " That's right, kiddies. This is the big one. The announcement we've been waiting to make for a long time now. G4 is now your official cable television home for the one and only Heroes, the television sensation that has held the world in thrall for the past year or so."
Beginning November 3rd,(tomorrow) you will be able to watch all of the Season 2 episodes of Heroes on Saturdays at 10PM ET.
This means if, for some reason, you missed a new episode on Monday night, you can catch it right here on G4 on a second night - Saturday.But that's not all! Following each new episode, stick around at 11PM ET for the Post Show. Hosted by Kevin Pereira and Blair Butler, this live event will take an interactive look at everything Heroes.
