Sounds like it wasn't super informative with only two real answers given besides telling people to buy specific issues. These panels are never that good because of the little amount of info they can give out.
My reasoning why NBC passed on WW is that they saw how dumb it sounded and felt even though they are in last place in the networks and are desperate for something but they aren't this desperate. I would love to see WW on TV but from what I heard and read about this pilot, I am glad that it did not get picked up.
@King Saturn: I think the Iron Man and War Machine were the best. They were really well done and looked like they had taken a lot of time to make and not just slapped together in a day. They were also really tall and I think that helped them out.
@miki: For the 3rd appearance, go to use Google to help out with his appearances and for Crossing the Chasm, like someone else said, find an annual for the book that features the two biggest people in DC.
