There is now a website for the Minneapolis / Hennepin County library merger.
The newest update is here.
It discusses some of the teams being set up to work on the merger. It looks like the Minneapolis system will be merged into HCL and Minneapolis employees will be HCL employees. As a patron of HCL, I hope this goes smoothly and there is increased service and access to works in Minneapolis (and, more noble, that the transition is smooth and easy for the employees, too)
