This is whats gonna happen, their gotta drop the current MacBook, and turn the MacBook Air into the MacBook, then they are gonna offer two versions. A plastic white macbook air that will be even cheaper then the MBA, my guess somewhere between 600-800, and the Silver MBA which will cost the 999.00 effectively covering a broad range of prices that Apple had never been able to claim before.
Then....pigs will fly. and Pink Floyd fans will rejooice.
