Main difference I see between this and the Titanium will be the Clock Generator. Aside from that they will be nearly identical with different color schemes. The lower overclockable memory support is a bit of a let down considering the other 2 X370 boards support DDR4-3200. The memory on MSIs boards are overbuilt so they should be stable much higher. I think the difference between now and March was that we didn't know how far AMD will push their support for memory standards. Right now on the Titanium I can almost get 2667mhz stable with 4 dimms. If they meant the memory can do that with 4 dimms, that would be pretty good.
For an X370 board right now, I would like an ITX with 1 PCI-e x16 3.0, NVMe, USB 3.1 Gen 2 Ports for Front I/O, 2 memory dimm, Wifi. Everything else would be superfluous.
