Oh, I was all for it from Day One. I'm an OT lover and have been since I was old enough to point one Kenner action figure at another and go "pew, pew, pew!" Even if the Big Three end up as little more than heavily hyped speaking roles without many action scenes it'll still be wonderful to see these guys donning the wardrobe of the Lucas universe once more.
Frankly, if Han Solo does little more than grouse to Chewbacca, complain about how things in the New Republic aren't as good as he hoped they'd be and then die in a blaze of glory I'll still think I got my money's worth. Han Solo is still Han Solo, and as long as Abrams, Kasdan and the crew give him a few moments of classic swagger I'll be smiling and wanting to watch it all over again.
