It's been more than a year since a beta site was graduated – the latest being Bitcoin in October 2017. Since then, the SE team has been busy with the rolling out of responsive design themes which simplified theming across the SE network.
As mentioned before, beta sites that consistently receive ten new questions every day will be considered for graduation. With this criteria in mind, a quick search through Area 51 found that beta sites such as Politics and Space Exploration currently consistently receive close to 10 questions / day and with mostly "Excellent" and "Good" for the other metrics.
So, seeing that the new theme is out on all sites, are there immediate plans to graduate some sites soon and which sites are they? If not, is there a rough timeline of when sites will be graduated?
