AMD are in the same position with CPUs - XT release.Like Intel Nvidia's high price structure is baked in, they have been doing it so long now its become a part of their revenue and margin growth structure, investors expect to see that growth to continue, its why the share value is so high, like a Ponzi Scheme, people throw money at Nvidia because Nvidia is constantly growing, the more they grow the more money investors throw at them.
All it takes is for Nvidia to have a couple of quarters where they stop growing or contract and people get nervous enough to start pulling their money out, that starts an implosion cascade.
Nvidia have to keep the cycle of growth going and that means increasing the amount of money they get from you again.
