Heroes online comics are soon to be published as a graphic novel by DC. I haven't read all the Heroes comics but i'll probably be picking these up. Also it's coming out in fall roughly the same time the DVD season 1 boxset is coming out so I wouldn't be surprised if there's going to be some special DVD boxset packaging.

We are very excited to be releasing the compilation of “Heroes” comics through DC Comics," said series creator-executive producer Tim Kring in a subsequent press release. "Until now, most of these stories have only been available on NBC.com. To have this first printing coming from DC, the premier publisher of comic books, is a dream come true. - Source

What is also exciting is that Alex Ross/Jim Lee are going to be doing all new covers for the graphic novel... Yippie!
