I was planning to buy a new MacBook this week until I heard about the potential upgrade that could happen during WWDC. I was just wondering, what are the disadvantages to waiting? If the new MacBook does something I don't like such as removes the headphone jack, goes to a haptic feedback keyboard what are my options? Will they still sell the old models for a short while? I am currently eyeing the 15-inch model with a 2.7Ghz processor, 512 GB SSD, Radeon Pro 460 and if they take the wrong direction with the new MacBook I would still like to be able to buy it. Would it be crazy to buy one a few days before knowing I can return or cancel the order if they end up announcing a new one?
