At CERN it is planned to have a working version of RDA3 by the end of 2013. RDA3 is a new development based on ZeroMQ instead of omniORB as RDA2. RDA3 supports 2D-Arrays and has a whole new API. This has an impact on FESA which relies on RDA. More information: http://wikis/display/MW/ (visible from within CERN's environment only).
