John - The point I was trying to make was in reference the last statement in your previous post:
"If a manufacturer wants to stop unauthorized resellers, all they have to do is track which of their authorized channels are selling to them and then put pressure on that entity to block such distribution."
That shouldn't be too difficult to do if Samsung gets a hold of cameras it believes aren't being sold through a legit source and traces them back by serial number, which does require some effort a manufacturer may or may not be willing to put money on for whatever reason.
Then again, this doesn't seem to be the case at all here if Samsung has decided to be more agressive on pricing overall for its existing models and is pushing those lower prices down through its distribution network, which is what it sounds like from one of your earlier responses:
"Samsung is being aggressive on price, especially active in the past half year, including promotions on certain products, consistent with OP's experience."
