Probably not much. I really don't think we're going to see them until Apple is good and ready. Yeah, kinda sucks. But I wouldn't spend the rest of July and all of August hoping for a sneak-peek.
Jobs will probably mention it, I'm sure. But just reiterate what's on the site already. "Yeah, we dropped the ball. We'll make up for that in September, trust me..." is probably about as much as you'll get.
