Here’s a few quotes from Reuters:
The Apple co-founder, a pancreatic cancer survivor who stepped down in August after his third medical leave, is expected to make an appearance, though a no-show by the Apple co-founder will not be a major disappointment.
“Most interesting is whether new CEO Tim Cook will lead the keynote and whether … Steve Jobs will participate,”
“Investors would like to see Steve Jobs to confirm that he is still involved, but we have dealt with the fact that he’s not going to be as involved,”
So as you can see, no one really knows if Steve Jobs will be there but of course, it would be great to see Apple’s retired leader at least in attendance.
