I believe Apple is not making huge profits on its MacBook Pro line (at least compared to the iPhone line and iPad line) and that they are trying to bolster their profits. One of the lessons that businesses seem to fail to grasp over and over again is just because you are not making huge profits on a product does not mean that the product is not essential to your business. Apple is starting to cut off their pro users. This will turn pro users away and with that they will start to lose business in not just their MacBook Pro and Mac Pro lines but that will bleed over into losses in their software business and other product and business lines. This will become a snowball effect which will eventually lead to Apple becoming irrelevant in the electronic/computer market place.
Really? Apple is by any real means the top tech company right now? The only pro uses that is cut off from their lineup is a niche market of video editors that need desktops for their work. And apple WILL release an updated Mac Pro when the intel timeline catches up and they can revive the mac pro with good specs. They didn't update it now because it simply wouldn't make since. Quad core kaby lake doesn't exist and apple knows better than to release a powerhouse desktop with year old processors, for laptops the 6th gen was fine as it will be relevant for everything but HIGH end video editing for the next four years.
