Looks like NBC is really trying to relaunch Heroes. They have a whole new plot and series of characters (a weird carnival), and these videos seem to want us to get involved with the show again, and get to know the characters we love.

The Sylar and Claire videos give a good background/recap of the characters, but the "Heroes in Love" one doesn't really make sense (some characters aren't even on the show anymore, and the Matt/Daphne thing didn't really happen), but they're good promos. (Here's the trailer for season four.)
