I have a 2009 Mac Pro desktop and long overdue in buying a new Mac. I've decided to go with a base iMac Pro instead of waiting for the new modular desktop in 2019. I'm not a video/film heavy user nor am I a gamer so I don't need the high end processors but expect to get 64GB ram and 2 TB SSD along with the high end video card as I typically keep computers for at least 6 years and believe I won't have a need to upgrade in that time period being a prosumer. I can wait till later this year if there is a good reason to do so but if the updates are only the cpu I'm not sure if that's enough reason for someone like me to wait.
