Hi, I want to ask how the MacBook Pro prices vary after each product release. Basically I'm looking to buy a new MacBook Pro 15" (non-retina) with lowest specs available but I'm wondering if I should wait a couple more months to see if the price will drop more as it gets older. I've noticed that the price for the higher spec non-retina MBP stays the same but the processor has had an upgrade of 0.3 Ghz. Does Apple tend to keep the prices and just upgrade the HW you get for that price? Thanks!
