It seems, once again, that Apple shares were bid into the product announcement and sold on the news (though it appears the selling has been front-run here). No one really knows what they will show but expectations are for a shiny new iPad which will wow audiences world wide until they start to use it and realize it's the same as the old one... (rumors include iPad Mini 2, iPad 5, New Macro Pro, New MacBook Pros, OS X Mavericks, and even Apple TV again...)
