RichardSkinner, Being how R2 is so new I haven't heard any official news on a date that it will be released. I am sure it is on the road map but engineering has to do all the testing and developing to ensure everything works the way it should. I would recommend to just continue to check back every so often and if I hear anything I will let you know.
Does anyone know when a version of the HIT kit that's compatible with Windows Server 2012 R2 will be released?
