It’s an ever changing concept to meet future demands. I would think that means it will be a long term thing which is constantly evolving, and since the future operating environments are somewhat uncertain/unpredictable ...the concept will be adapted accordingly to best deliver in those environments. The finish won’t be set, nor will its ideas be set.
Some rumors will come and go, yet some common themes will actually be developed (e.g the theme of smaller teams and having Commandos working in a littoral strike group).
Once it does ‘finish’ the next concept will be thought of, experimented and slowly implemented. It’s a rolling process. Should be plenty of exciting opportunities hopefully!
Just my two pence, would be great to hear other’s view
