I am guessing they will release them but they will be plagued by non-adoption and to the extent their is significant ETH in play, they will be attacked either to steal ETH or short ETH and crash the ETH price.

I am expecting a centralized clusterfuck (much more dire than Bitcoin's current scalepocalypse) originally marketed as decentralized nirvana.

Of course it is also possible it could unravel before that and they abandon with their tail between their legs, but I doubt this because one assumes they raised more $millions in the recent pump.

The chance of them solving the underlying insoluble fundamental flaws is nil. There is no way to do sharding of smart contracts without breaking the Nash equilibrium that creates a majority consensus instead of many competing forks. There is no way to arrive at consensus of off-chain events without delegating consensus to trusted centralized entities. It is a huge clusterfuck that Vitalik weaved.
