I don't think anything is wrong with Jobs.
If you read other articles, this seems to be more about Apple having a very poor relationship with the people that run the show (IDG).
Plus they also want to switch away from having Steve Jobs as their sole figurehead, since their stock plummets everytime he's rumored to have the flu. So I presume they will have different people announce products, and start throwing their own press events whenever they need to announce something.
