Do they release more technical information on the exploits after the browser makers have had time to produce patches? The things these guys do always blow my mind. At the same time it just reinforces the point that if you are targeted by an entity with enough resources there is pretty much nothing you can do to prevent exploitation. I am pretty sure all browsers get "pwned" at nearly all of these competitions.
