He IS that bad. He's always puffing and acting as though he and he alone has the inside track - when often there's not even a train.
He could have been honest and said that, as usual, Petrie is playing everything very close to the vest and that he, Grant, will try to bring any news to his listeners just as soon as he, Grant, learns what he, Petrie, is going to do...but that no one should hold their breath.
I am so glad I don't get KHTK. It's probably saved me numerous nervous breakdowns and possibly even incarceration for threatening phone calls.
