Personally, next summer I am hoping for an update to the P570WM to include DDR4, PCIe4, dual sli, and support for Skylake-E and Xeon, with 4K 17" screen, and, depending on what size DDR4 sodimms will be out, support for 64GB or 128GB (basically a mobile server, since we already have DTR). With this, support for the new eDP 1.3 I believe it is which allows 4K at 120hz and 8K at 60hz, or any newer standard released between now and then. Obviously, the SLI support MXM or any new standard that is present at the time, so long as it provides for swapping out cards and updating. The external connections are negotiable (thunderbolt, DP) but a couple USB 3, an HDMI, esata. I am still holding out on whether it should have an optical drive. That depends how the P770ZM treats me. I do not need it slim, this is not just another desktop replacement. It is a mobile server capable machine!
