That would be true, except that the manufacturers have decided to not make any AFCI receptacles. (I heard this from John Cangemi of UL at the IAEI workshop in NY State) Even though they have submitted working units to UL for approval, the decision was made that there wasn't a large enough demand to warrant the production of mass quantities at this time.
I'm betting the decision was really based on the fact that there is a higher profit on the CB over the AFCI receptacle.
