What a great panel. I haven't looked above to see what's there but the big news to me was:
1) Ed Norton rewrote the screenplay.
2) They showed The Hulk concept art. Pure awesomeness.
3) There will be a small cameo or hints of other characters in the Marvel Universe just to show the Universe is tied together. They way Ed Norton sounded...it looks to be Captain America. He used that as an example but they way he led into that makes me believe this.
4) They were shooting for 2 weeks and were flying back right after panel. I tried to wave Louis down and I think he saw me but was walking with a crutch or something behind the stage and had to keep going.
Whoa! I missed all that... where is the quote where he mentioned this?
