Have they decided upon the block numbers already?
Not yet.
In the discussion on drafting the EIP those devs who wanted to delay the bomb were advised to simply copy the last bomb delay EIP and adjust the block offset value to add 400,000 blocks. This value may change, so we'll have to wait for the EIP to be published.
wow, that's why odds on "By 1st September" dropped from like +105 to -150
Merge is indeed coming in Agusut

Its simple they will push it out if coin is over 2k
They will let it happen if coin is under 1k
the gray zone is 1-2k
If only the merge could be decided arbitrarily by the price of ETH, kek.
No, they will keep on pushing it and commit the merge between PoS testnet and mainnet. There're maybe some delays, fuds but they're hell bent on doing it, not by any price range but because the ETH has been stagnant for a while. If they keep on the delay like times before, they will hurt ETH furthermore, a self-sabotaging act.
It is because pos = piece of shit and death for eth.
So if they delay and eth crashes to 800 they push it forward to save eth ------ and eth dies in 1 or 2 years. their defense is at least we tried to save it.
If they move in august with prices in the 1500-2500 range and eth craters - they crushed eth and have no defense.
If you don't agree it does not matter this is what is truth. "Or maybe it is what I believe is true."
Now the problem is Mr V.B. may actually not give a fuck about rationality and truth. He may go contrary and follow your lead and logic. Hoping for a big pushup in price before the crash.
It will be fun to see if Mr V.B. decides to go your route as the crash of eth will truly be spectacular If he goes pos in August of 2022.
