Well, I happened to watch the live coverage of the keynote of the ceremony last night. And that showed some major advancements in this new gadget. Almost 200 new things, both on hardware and software sides. Faster BT, fastest WiFi, Thunderbolt connection with a lightning port (9 pin) double sided, A6 processor, unibody hard casing with ultra-fine edging, LTE support, longer battery time, panoramic recording, HD facetime camera, iOS6 with several new apps, more smart siri and several others.
