ETH spot etf likely?

Is a ETH spot etf beside btc spot etf (before/within/ after approval) likely?

Are there any filings for such etf‘s atm?

Are there any reasons why a spot etf for eth has to be handled different in approval process from the pov of the SEC?

I have these questions, cause i mentioned a lot of speculations and hope for the blackrock btc spot etf fiiling, but never heard similar for eth.
