I decided to hold out for another few months before getting a MacBook so I can see if an Air Retina is released and what sort of price tag and specs it may bring. But in the meantime, in case one isn't released, what usually happens to the prices on the older models (whether new or refurbished) on the Apple Store or in the retailers that carry them (best buy, adorama, BH)? Do the prices drop like a rock ($300?) or are the discounts much more modest? Anyone have real examples from past refreshes?
