More delays of ETH 2.0 would be great, but as I understand it, even when implemented, it will now be a hybrid method that still allows mining during a transition period. Many have speculated this could add 1-2 more years of mining for ETH. What i have not seen directly addressed is the whether or not the block reward for mining will still be a minimum of 2. If that is reduced to say 1 or 1.5, it may make it difficult to profitably mine ETH since the premium fee portion (addition) to current block rewards is expected to be significantly reduced with 2.0.
what if the hashrate of new cards can now do 100MH? may change your calculation hehe.
anyway, i like to point out that sometimes some miners are the last bagholders of their cards, the profit in between upgrades are better than one time selling. during upgrades high end cards is more easier to sell, you gan give very big discounts since the card ROI'd several times already,
miner1: hey kid wanna 100$ 1080ti?
