We can only assume the new iMac 2018 version is just around the corner, and will probably be announced if Apple hold an 2018 iPad/Mac event. I normally upgrade each year, and sell the older version right before the event. But now I´m having second thoughts because after iMac Pro, I´m not entirely sure Apple will allow user-upgradable memory. Who thinks Apple will still allow user-upgradable memory, and who think it might be hard soldered to the new iMac? Have I missed any rumours on this? What do you guys think?
