Actually I've heard the Air will be replaced by a new Macbook Helium. So light it actually hovers above your lap. It also use a new poison ivy bridge which automatically eradicates anyone that tried to steal it. There will also be two Thunderbolt ports, and a new LightingBolt port that opens a worm whole into Steve Jobs mind. It's RAM is actually in the cloud (its called ThunderCloud), and it boots so fast you can't even hold down the option key in time to dual boot if you wanted to. One time they left one unattended and it ended up knocking up an iPad 3 and an iPhone5. They had tiny baby laptops. If you hold it sideways, it turns invisible. If you look at it too long it will seer the image of an Apple Logo into your retina. I actually have a prototype one, but if I showed it to you it would kill me with its powerful built-in laser. It runs iMacOS which is a new hybrid OS that was written completely in subjective C. And all of that will cost you just $999 and the cost of a gallon of apple kool-aid.
Oh, and you can actually download it from the new online mac hardware store.
