The pricing for RDA was made public during the last few days at the ALA mid-winter conference. The link below is to an RDA forum which includes a posting about the pricing as well as other RDA-related information.

There is no information available yet on pricing outside the U.S.
If I hear anything further on this I will send it to this list
cheers
