The comics that Hakeem mentioned are probably not going to be in the upcoming movies, as the movies are about to start shooting while the comics aren't even finished yet.

The parts which are more or less confirmed to be in the sequel(s) are "A Dame to Kill For" (starring Dwight and Marv) and "Hell and Back" (starring a guy named Wallace). The latter is apparently long enough to warrant a movie on it's own. But they might shorten it a bit, who knows [img]i/expressions/face-icon-small-tongue.gif[/img]

Anyway, I really want to get into the comics more. And those upcoming ones sound really cool, especially Hartigan's past. Developing his character will make his death even sadder. ;S
