Just remembered. For those that haven't seen it yet, here is the 75th Anniversary panel from Comic-con 2016:
For me, the best thing was seeing the legend (though I am sure some in comic-dom don't agree) Jim Lee talk about the character. Her history, evolution and what they are trying to do with her in the modern take. Also, current WW artist Nicola Scott, hearing her take on it was a great insight. Really good talk.
