Sounds about right, when you look at all the TF products released by Hasbro this year, the ones focused on the same sort of collectors the 3rd parties target would only be a small percentage of the amount of merchandise they pump out.
I'm sure of third party products started selling their wares in Wall Mart and departments stores then Hasbro would be spurred to action. But I doubt they would do that and as long as they remain a niche market I doubt it's too much concern to Hasbro. The extent of 3rd parties influence the situation probably appears larger than it is to people like us who are the niche the 3rd parties target.
