You think that "story" is true?
Let's be honest here, Nvidia (or AMD for that matter) don't really care who buys it, as long as they are selling it to someone.
There is no possible way to stop miners without having custom firmware that looks for mining patterns that would stop the mining programs, which can easily be done, yet, they don't do this, since they love selling cards.
Micro Center has been doing the 3rd card is $10,000 for >6 months now, as if that is gonna stop miners from paying people to pick up 2 at a time, they are STILL mostly out of stock.
Nvidia already sells specific cards by themselves via their site, if they do this for their whole line, all their AIB's will be pretty pissed off.
Right now, the whales are bypassing the retailers, and ordering directly from the AIBs, which is how they can get drop shipments. AIBs LOVE that, more $$$ for them.
Retailers will get small batches, and that is about it.
