I was the kid who peaked at his presents before Christmas. It's just my nature to eat up any tidbit that gets leaked. I'm sure we'll have a trailer this fall but more than likely it's going to be a teaser trailer with little information about the plot. Probably closer to Christmas will they release something with a bit more substance. I'm guessing around that time the marketing/merchandise folks will have their hands on whatever plot/character data they need to do their thing and more info will leak.
