The iPad 5 is expected to make an appearance today. Rumor has it that the device will have a complete redesign to mimic the iPad Mini, along with an A7X process, 8 megapixel iSight camera and Touch ID. A recent report claims that Apple might also unveil a new type of Smart Cover that has a keyboard implemented into it, similar to Microsoft's Touch Cover.
Next on the list, the iPad Mini 2nd generation, which will most likely have a Retina display, A7 processor, 8 megapixel camera, and also Touch ID. Loads of reports came in saying that the iPad Mini might not have a Retina display this year to shed more light on the new iPad 5, so hopefully they're wrong and we'll all get what we want.
Other than that, Apple is expected to show off the new Mac Pro, Haswell MacBook Pro models, possibly a new Apple TV, and OS X Mavericks should make an appearance in final form. Those who own an Apple TV already will be able to live stream the event right off the set-top box when the event has begun.
