Hi there, Marc just covered off on this during the livestream, which will be posted to YouTube. Revit is on the list of packages we’re looking to support through Datasmith. No timeframe to speak of just yet.
If you’re working in architectural design, you may want to check out Twinmotion 2018, powered by Unreal:

They demonstrated their Revit to Twinmotion workflow at our SIGGRAPH User Group, and we’ll have that full presentation posted to YouTube soon as well.
