If you look in the ICE News and discussion section of this forum you can find monthly topics called "Director Briefing [month]", where Nicholas HM Caldwell keeps the community up to date with all the projects. As far as I understand RMU will probably come out later this year, but we will get more precise informations after the so called "RMU singularity event", which is basically when the work is close to an end and they can speak of dates with a reasonable level of approximation.
That of course is just what I undersood.
