This is just a few retailers jumping the gun. A full list is expected soon. However I'd say a good guess is that whoever had the Terminus Armor and Blackstorm will have the Valkyrie/Defender and everyone else will have the Argus. Chances are higher if said retailer was a subsidiary of GameStop, as WB Games is here in Australia. Although it has been two years, so perhaps BioWare's retailer relationships have changed.
