My translation - I'm so so happy and thankful!
It might be that Jenny_O is right when she says this: "looks a lot like the original message, and under 'Read more' the original message stated that 'By late July, creators will no longer be able to revert to the legacy Blogger interface.' This sentence appears at the bottom of the message."
The message that states, that Legacy will not be accesible after the end of July has not been updated since May 20th.
We are allowed to hope that Blogger has become wiser.
