Today there was a post on WordPress.org’s Make WordPress Core Blog called Introducing Twenty Nineteen that introduced some information about the upcoming default WordPress theme Twenty Nineteen that will possibly be released late November 2018 unless it gets held back to be worked on some more:

Some of you may know that for several years in a row now I have tried to keep up with news on the default themes for WordPress each year, throughout each year I do random web (internet) searches, and I search through various official and unofficial Automattic/WordPress blogs and websites including some that belong to some staff members (employees) trying to get early news about the default themes for WordPress each year.
This is usually not easy and finding this information is usually hard because most of those blogs/websites do not talk about this usually, except some of the WordPress.org blogs/websites, which I usually do not look at or follow because I am only a WordPress.com user with a free account so that led to the Twenty Thirteen theme slipping under my radar even when I had tried to find information about it so I was surprised when it was released suddenly years ago without my knowledge of it even being worked on yet or discussed yet.
