New Heroes to Return to NBC

I remember watching Heroes back in 2006 and after the first season, I was hooked.  I loved the heroic tales with the comic book twist and I could discuss it with my "comic book nerd" friends without getting in an argument over the origins of characters like they do with the older DC or Marvel books. The second season or Heroes came and was a huge let down. The third season showed a but more promise and the fourth , well, I wasn't surprised when the series got cancelled.

NBC just announced the coming of Heroes: Reborn for 2015.  nothing has been said about the plot or who we will be seeing as the new (or old) characters, but I am curious as to what they have in store for the shows revival.
