Rick, 5.0 will come out when Gutenberg is ready, not vice versa. That's the idea behind these new feature-driven releases. We will still have target dates, because that helps us think about scope, work involved, and plan for all the supporting documentation, translation, and marketing material to be in place, but we're not going to push out 5.0 until Gutenberg is something the team working on it and myself agree is ready.
