MXROAD V8i (SELECTseries 4) - Discontinued Support and use of Input files

We recently received an email with respect to an update to the Bentley Support Policy.  Many people in the office took this as a discontinuation of MXRoad but it is unclear if this is the case.  However, we do note that MXROAD V8i (SELECTseries 4) will have "expiring support" from 1st July 2019 i.e. it will be unavailable for download and that "Connect Edition" and "Open Roads" will replace MXROAD.  However, a lot of our designs use input files and we are concerned that this may not be supported. Having not used Open Roads, can you advise whether input file functionality is or will be available?
