There is the following in the KSK rollover plan: 
"The Design Team is unaware of what specific 
objectives would be achieved by delaying a KSK 
roll".  The plan was put on hold because of the 
data from September 2017.  At the moment it is 
unknown if/when there will be a KSK roll.  Is not 
doing a KSK roll by 2020 [1] a viable option?

1. The date is based on a statement in the DPS.
