Even PH got messed up. They had the teaser date up and had to pull it.
You're thinking of SOL, but your point remains valid.
Also, remember several years ago when Al announced in a magazine interview that he was in the running to be cast in a CGI animated film? I asked him about it shortly thereafter, and he said "It's looking like that film isn't even getting made now. I get all excited about these projects and I want to tell everybody, and then they don't happen."
So yeah, I don't blame him for keeping this stuff on the dl. Let's focus on getting excited for the things that WILL happen - the children's book and Album #13!
