Generally speaking, that's my understanding.
There are also a lot of paris that were simply faked too.
I don't know how many "scrapped" pairs after production there are, nor do I know that there is a definitive way to say that this pair is a scrapped actually produced pair and that one is a fake. So, for my money there are only 4 CONFIRMED legit pairs - the 4 samples that got sold at RIF. Beyond that, I think it's all in the realm of uncertainty.
There are fakes that were made with the sample tags. We know those are fake.
But, whether Joe Sneaker guy who is super legit because he owns Eminems or whatever has a legit pair or not, I think it's hard to know for certain. And, simple probability would state that a bunch of people think they have real pairs really do not.
If you haven't discussed this with John from the SB thread, I think it would be worthwhile to ask him too. He has opinions of this as well.
