I just don't see the point in this. All it does is shift the modular cables to that huge power bar and if anything it will make cable management harder not easier. I reckon that these will be a massive flop.
The DC cable between the PSU and the CONNECT is not planned to be modular as it's mandatory to use it and it's not the same pinouts as usual ATX 24 pins. PSU is specific to CONNECT and so is this cable. But as you may have seen, between CONNECT and components, it's fully modular. While we cannot say that it will never be changed, for now, it's not planned as far as we can say.
