An action cannot please every body, like the ETH merge, many are hyped about this merge while others are having a doubt. So it is not surprising that there are people who are a bit hesitant to par take in this merge event. And I think most of them are POW miners.
Because of unclear plan for this merge, many are hesitant to make a move for now and they are just waiting for the day of merge because that is the only time we can know the result and effect of this update. I still have no plans for this, don’t even know yet if this merge will be good for ETH itself, but then again I’m very positive since ETH can’t afford to make any mistake and with this, I know they studied this very well.
I think it's not that the plan merger is unclear, they already have the date. It's that suddenly there is a group of miners who suddenly will go for the split, hence ETHW although they already have the the Ethereum Classic.
So the expectations for this hard fork and the free airdrop is not going to be easy for us ETH holders and that's where a lot of questions arises including how and when they are going to get it, what will be the prie of ETHW or whaever they call the split chain coins.
