The OCLC Research Library Partnership will launch on 7/1/11.
Here's an excerpt from the announcement:
The OCLC Research Library Partnership is a new entity that will replace the RLG Partnership on 1 July 2011 and is a locus for OCLC's increased support of the research library community. It is an organization born out of the successful merger of RLG and OCLC in 2006, when expert staff from the two organizations were blended into one team with a combined effort directed toward supporting research libraries and archives. The merger created a venue where affiliated institutions could collectively identify, analyze, prioritize and design scalable solutions to shared information challenges. . . .
OCLC recognizes the valuable contribution that research libraries play in the cooperative and wants to provide a specific venue for engagement around shared issues. This venue is the OCLC Research Library Partnership, and it represents OCLC's renewed commitment to the research library community. OCLC's increased investment in the Partnership enables a significant reduction in the annual Partnership dues, which will, in turn, enable a greater range of institutions to participate in the Partnership in the future.
