Note the 20 series bombed, largely because of the price hikes coupled with meager performance gains, so the initial plan was for the 30 series to be much cheaper. But then the 30 series scalping happened and they got a second go at re-anchoring what people thought of as reasonable GPU prices. Also they have diversified other options if gamers won't pay up, compared to just hoping that GPU-minable coins won over those that needed ASICs and the crypto market stayed hot. I can see nVidia being more willing to hurt their gaming market for AI than they ever were for crypto.

Also also, AMD has pretty much thrown in the towel at competing for high end gaming GPUs already.
