Seeing BB-8 actually roll out on stage yesterday was even more mindblowing then the trailer. What a cool piece of tech that is. I wonder how much that cost to make, I also wonder how many remote control BB-8 they will sell this Xmas.
I think the weakest link of the trailer was old solo, but I've always thought that relying on the old characters was a mistake. Hoping the story really focuses on the new characters. I'll settle for "old luke", but that's about it.
