Your guess is as good as anyone else's when it comes to prices.Thanks Tankmaze for your honest opinion if I do wait will it been a significant price difference?
Usually list prices on like for like equivalent models stay around the same as the outgoing model list prices. Healthy discounts will be available on the outgoing models. Sometimes the spec will be enhanced (more RAM, bigger SSD) and the price will not increase. Sometimes the price will drop like it did a few months ago with the iMac. Sometimes the price will rise significantly when a new and expensive technology is introduced, like when retina screens were introduced. It's a bit of a lottery.
