Six million units could be considered a reasonable success, but I think 10-15 would be considered a stronger endorsementfor a first edition VR peripheral. I suppose it depends on software, if Sony can get some killer IP's the attach rate will be higher, but assuming the PS4 wil sell 80-100 million, I think a 10-15% attach rate would be a reasonable success.
