I just can't see Apple doing this. I've been wrong before but lets just take in what they'll have if they do that.
Apple will have a series of 11", 12", 13", 14" and 15" laptops. I think that's just overkill, perhaps they'll kill off the MBA line at that point but I don't see a huge need for a 14" laptop when they already have a 13" and 15" laptop
