I contacted them directly into the discord and received an answer. I post it here for all having the same questions :
“In the beginning days of the fork, you'll be able to interact with the same SteemLeo community on the Hive blockchain (using Hive.blog) or Steempeak Communities (when they're ready).
The Steemleo interface and LEO token won't be ready to move to Hive right when the hard fork happens.
A full post explaining what SteemLeo will be like post hard-fork will be released tomorrow.”
Thanks again for all your work and replies. Go on your great work @nickyhavey
