I don't think this has anything 'bad' to do with Steve. I think it is just Apple scaling back on expenses and playing it safe with what they 'need' or 'do not need' to attend. What is the point of doing more Macworld's if their sales are strong and they can save a few hundred thousand dollars at the same time.
Personally, I find it a shame, as I really enjoy the events, but at the same time I do understand why.
