Heroes : who's back ?

According to Kristin, "A well-placed source tells me there appears to be a plan in place for when the show returns, and it involves Kristen Bell, David Anders and...yes, Adrian Pasdar and Ali Larter all back in the mix and most likely as series regulars."
 Concerning Niki, Kristin previously stated that " No [Niki is not coming back]. But that doesn't mean we've seen the last of Ali Larter. I'm hearing that the plan as of the last time the writers met up (prestrike) was for Niki to be dead-but for an alter ego to take over. Not Jessica, not the whipped-cream chick from Varsity Blues, and that leaves... someone we've seen before. Of course, all that is subject to change due to the current holding pattern"
It sucks if Niki is really dead !! What about Micah ?!! He already lost his father !
Well, we'll see what happens ! Probably not before next september or october though !!
