This isn't so much a prediction as a theory. Basically, I'm asserting that Apple must and probably will either a) update the laptops aggressively or b) introduce a killer new model in the line-up. The reason: Apple can realistically dominate the market for laptops. Laptops are slightly encroaching on desktops in market share. So, if Apple dominates laptops, they dominate PC sales. This is their last chance for market leadership in a short timespan. Simple, really!
