The title is slightly misleading talking about miners, but the article is clear enough - developers and pools representing a majority of miners have agreed a roadmap. They've got consensus in as much as they've agreed the roadmap. But it's not until that roadmap is complete, and miners* can be seen to clearly support a hard-fork that consensus in the Bitcoin-protocol sense occurs.

* and nodes? I used to be a miner, long ago, but never really paid much attention to nodes.
