A new report posted by the Wall Street Journal this evening reveals that Apple's Titan Project Head may be leaving the company. A person familiar with the matter said that Steve Zadesky's departure was for personal reasons and wasn't related to his performance. But that's all that the WSJ really has at the moment. Speculation then takes the reigns and starts to assume that the departure means that Apple's secretive project may be in real trouble. If more tangible information is made available, we'll write a follow-up report.
