He is locked up until the offseason of 2011 and even then, might decide to stay as he might become his team's starter at that point. Short of Les Alexander's pockets deciding to go on a diet and a few other unlikely situations occurring don't expect Llull anytime soon. And even then, kid is still going to be a 2 round rookie, it will take half a season or so for him to get good.
yes, you'll see him in summer league if he is not brought up to fill a roster spot because of injuries.
