I understand that but I don't think it has anything to do with his passion. I think it's a combination of his new job responsibilities, marketing essentially hand cuffing him to secrecy/taking total control, and I ultimately question how close he really is to every detail of HHN at this point. With things like Nintendo World, Fast & Furious, etc. in the works, who knows what's really on his plate on a day to day basis.
To add to that, he's essentially become the spokesman for Universal. He does press tours all over the globe and even goes on camera to promote new things happening on both coasts (e.g. the Harry Potter Christmas experiences). He's a piece of talent that they've invested in and I totally get it. Unfortunately, that leaves all of us on a sad, lonely island craving for any of legitimate information.
