You said his new project is Doblon/louisd'or. I didn't find anything on Github or on the web. What is your source of information? Where did you see that work? How can you say it is good?
The coin he left BBR to work on is Louisd'or (

If you read the Louisd'or thread you will see that beta software has been promised a number of times - the last time it was promised was in March and
since then there has been nothing, not even a post to explain the delay. It looks like another abandoned project.
CZ is flighty, nipping from one project to another, which is fair enough, but it leaves investors in the shit.
This coin needs a full-time director, not some brilliant, but erratic dev.
