It's not about products in the pipeline, or even the culture
And it's not going to change now, because he's still chairman, and still alive.
Once Jobs has left as Chairman, they've got a bigger problem. Who points the company in a particular direction? When different executives, product managers, etc. don't agree, who can really wrangle them? Jobs. It's not clear that anyone else can make decisions that step on toes and not drive out talented people at the same time. We've seen that happen at any number of companies, including Microsoft. It's easier to put up with s**t when you think you're working for a Messiah. And, having some idea of group dynamics, you're going to start to see a cultural divide (caused mostly by existing employees) between those who were hired during the Jobs era and those hired post-Jobs. And human nature being what it is, they may be insufferable jerks about it.
Then there's the question of negotiating with other companies - studios, music labels, publishers, wireless carriers, etc. They're not going to be "afraid" of Apple without Jobs. They're going to push back, and push back harder then the newspaper and magazine publishers did over the subscription fees.
And then there's the media. Prepare for an onslaught of "Has Apple lost its way" articles. Missteps smaller than some that Jobs made will be blown out of proportion and be seen as signs that the company is adrift. A fawning press has been part of the Apple PR machine, and they may turn on the company quickly once Jobs is completely out of the pictures.
So, in the short run, no change since he's still a presence. After that? They've got a problem.
