well given that we've had zero leads so far, I'd say that the fellows over at LEGO are being pretty good about it. And yes, I see the appeal in being surprised by the sets when they are released, but it's also kind of nice to see them before hand. makes us feel kinda special.
Personally, I think it'd be kinda neat to get some blurry pics only, then get the official teaser, then get prototype pics. It would keep us guessing right up until it's about time for Toyfair.
