Well you never know its not out yet.
Just hoping BW works well & they keep with having options to set 60/75/80hz+ on the 5k & 8k.
*60hz support asked about for folks with Optimus? Laptops that Nvidia paaa through the intel igpu(which restricts to 60hz)
With the 8k it would be interesting to have a 1080p / eye with 90hz if its mainly a bandwidth issue.
