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.
