Since thousands of people complained about Heroes panel being in the smaller 2500 seat (Ballroom 20) as opposed to the 6500 seat (Hall H) they posted the panel online. FYI NBC didn't want to have a bunch of empty seats in Hall H that is why they asked for it to be shown in Ballroom 20... how blinded were they... Heores is huge and could have filled all of Hall H.
Anyways... here's the video
