Once ETH goes PoS you will be able to buy ANY gpu at 50% discount over REAL MSRP.
And i aggree with you. This companies are going to have a tough time trying to sell their overpriced GPUs.
GPU mining is already dead. And gamers are way way way in lower numbers that they bragged about. They are just a small amount. Every single miner could be easily counted by 20 - 30 gamers. Even myself.
so this prices will have to go lower, or they will rest on the shelves nearly forever.
