I think Steve wil come out on stage and bring us up to speed with what's going on with 10.2 and some iApps. Maybe Steve will later show us some new Switch ads but it's highly unlikely he'll start the expo with them.
You and me, iGavina, we're in the same boat, which is actually scary when you think about it!
Usually Steve Jobs has been focused on extremely descriptive information and demos of Apple software, such as iPhoto, and hardware, such as the camera. I would expect Jobs to use the expresssion "See how easy it is to..." and sort of part emphasis on peecee users multiple times, rather than make a whole speech/lecture campaign at an Expo. An Expo is where you get to see cool ****, such as new Apple products or software, and not to have a lecture.
