The new Gutenberg editor is due to arrive with WordPress 5.0 on November 27.
We're already starting to see new types of Gutenberg-specific plugin. These aren't old plugins that have a layer of Gutenberg comptability. These are new plugins that are block-first. They're built for the new Gutenberg era.
- Better versions of the default Gutenberg blocks.
- Entirely new blocks not covered by the Gutenberg defaults.
