My suspicion is that these might just fit into the *A mileage upgrade system (as I would assume they do today), but will it be different domestically after "mid-2010"?
While the answer hasn't been publicly stated odds are that mileage upgrades will be part of the reciprocity just like EUAs/UDUs will be. You can currently use the *A upgrade program on the flights but it isn't as good a deal as the "native" upgrade options that each carrier offers.
