Some of this has already been out there for a while, but there's new stuff too. I'll just run down all of it (and I hope I'm getting this right from my memory):
• Savannah Weaver is an important thread in the Resistance and she sacrificed her mother to get John Henry made.
• John will find John Henry with Cameron in his chip and through some complicated process, Cameron is remade.
• John will have have to choose between Allison and Cameron (and he implied that he'd choose Cameron).
• Danny Dyson will be a major character and he is bad.
• Sarah Connor is alive in the future "doing things" (and not because she jumps ahead).
After the panel, I snagged his name tag off the table. And I got to meet
drenkrelar (sabaceanbabe was there too). drenkrelar and I walked and talked for a bit then a passerby joined in our TSCC conversation. :)
