May 25th article from Reuters that sheds some light on some new cast members.
Hit shows add cast members; new series rethink some roles.
The 2006-07 season is barely over and the broadcast networks announced their fall schedules only a week ago, but buzz has started about new characters being added to returning hits next season and roles being recast on the newly picked-up rookie shows.
NBC’s Heroes, which wrapped its freshman season with an explosive finale Monday, is rumored to be introducing at least four new, mostly international, characters next season, among them a sexy boyfriend for everyone’s favorite cheerleader, Claire (Hayden Panettiere).
Also potentially joining the cast of characters on Heroes next season are a 28-year-old black mother, a surrogate for Niki’s (Ali Larter) son, an Irish mobster, and a twentysomething Latina. It is believed that most of these characters will only do arcs on the show rather than become regulars.


Link?
I read about that. They have more updates on exactly who they are.
I think it’s gonna be hard for me to get used to so many new people.
when will the latest heroes season 2 be?…
heroes the best
But why they don’t said anything about the main characters? I really like to know what is happened with Peter!
he blew up…
He blew up, but there’s no reason that he shouldn’t survive: Ted was fine when he blew up, plus if Peter fell, he could regenerate. Nathan is probably dead, though :’(
WHEN IS BEGIN DA 2 SEASON OF HEROES?

What???? September??? I don’t !!! I’m a heroes’s possionate french. Oh my god ! I never wait so long. :-S
