Walking Dead Season 2 Comic-Con Panel 2011

The Panel at Comic-con was great. Now if they would just show us more about Season 2 of The Walking Dead! The trailer just has me asking more questions. Like what happened to the little girl that Rick was carrying at the end? Did she get bit? Did she get knocked out? And what about when dude cuts his arm? Is he a gonner? I didn't see him on the panel :)
