Diff bomb hasn't been set yet. There was a talk upcoming on 13/05 about whether to set it up now or delay it since record of diff bombs goes off, avg transaction's time increase and hurt the ETH ecosystem in a short term. Though I do think diff bomb is needed if ETH wants to move from PoW to PoS. This late release of 100% unlock hashrate for nvidia LHR cards feels like a prisoner's last dinner, really. Don't know if it was good news or bad news since ETH diff for now will increase further.
I think it will take this entire month to know for certain. Even devs aren't sure whether they can push a stable merge with all clients before the bomb. But there's a good chance of merging before August or Sept. Recent shadowforks are going pretty well with minor bugs.
But there's still a chance of another hard fork delay lol
It's like a Hitchcock movie, we won't know for sure until the last week(possibly last day) of this month.
