Honestly don't see how the report will have an details besides 'loss of control for unknown reasons'. No FDR or CVR so not much to go on unless they were able to find something in the wreckage which I suspect will not be the case.
It does appear to have some similarities to a Citation crash in Cleveland also in 2016. So maybe there is something there.
